4.4.2 Extension of DSS-X types
|
The present document extends three types defined by DSS-X core v2.0 [1]. These extensions are contained in the JSON schema file "19442jsonSchema.json". The extension mechanism is implemented using the keyword "allOf" as specified in "JSON Schema Validation: A Vocabulary for Structural Validation of JSON" [15]. The types that are defined as extensions of DSS-X types are listed below: • OptionalInputsVerifyType extends dss2-OptionalInputsVerifyType. It is defined in clause 5.1.4.1.3. • OptionalOutputsVerifyType extends dss2-OptionalOutputsVerifyType. It is defined in clause 5.2.3.1.3. • DocumentHashType extends dss2-DocumentHashType. It is defined in clause 5.1.3.3.2.3. NOTE: The present document defines this new type extending dss2-DocumentHashType because this component has to have an additional component for containing a PDF field name. This is required for allowing to submit the digest document when the client requires validation of PAdES signatures. The present document defines two additional new types that are built on some of the aforementioned types, namely: • InputDocumentsType, that builds on DocumentHashType. It is defined in clause 5.1.3.3.1. • VerifyRequestType, that builds on OptionalInputsType and InputDocumentsType. It is defined in clause 5.1.1.3. ETSI ETSI TS 119 442 V1.1.1 (2019-02) 17

5.1.1.1 Component semantics
|
The message for requesting the validation of an AdES signature to a remote server shall contain components for: 1) Submitting either the signature to be validated or a reference to the signature to be validated when this signature is enveloped within a signed document. Clause 5.1.2 specifies semantic requirements for this component. 2) Submitting the signed document(s) or representation(s) of these signed document(s). Clause 5.1.3 specifies semantic requirements for this component. NOTE 1: When the signature to validate is separate from all or part of the documents it signs, the signature is placed in one component and the signed document(s) is (are) placed in another component. NOTE 2: When the signature to validate envelops the signed document (this is the case of a XAdES enveloping signature that is not embedded in other document -a XAdES signature can envelop one document and be embedded in another document- or a CAdES attached structure) or it is placed within the signed document (this is the case of a PDF document with one or more PAdES signatures, or an embedded XAdES signature), signature and signed documents are placed in one component. 3) Identifying one or more protocols and/or profiles that the request message is compliant with. The first one of such components shall have the following URI as value, identifying the request message as one that has been built using the "validation" protocol specified in the present document: - http://uri.etsi.org/19442/v1.1.1/validationprotocol#. This message may contain a unique identifier. This message may contain an identifier of the service policy the client requests the server to use for processing the signatures. This message may contain other components for requesting to the server additional features. Clause 5.1.4.1 lists these optional components and contains references to clauses that specify semantic requirements for each component.

5.1.2.1 Component semantics
|
The protocol shall allow including the signature in different containers according to the following rules: 1) If the signature is an embedded AdES signature, the embedding document and the signature shall be placed either: - within one sub-component of the input documents container; or - within an underlying protocol attachment. In this case, a sub-component of the input documents container shall include a reference to the aforementioned attachment. Additionally the signature object container shall contain a reference to the embedded signature. 2) If the signature is a non-embedded AdES signature, it shall be placed within the signature object container. 3) If the signature is embedded AdES signature and the digest of the embedding document is submitted instead the document itself, then the AdES signature shall be placed within the signature object container. NOTE: This implies that the protocols defined in the present document support submitting several PAdES signatures embedded within one PDF document, if this one is submitted to the server. However, if the client submits the digest of the document, the request message can only have one PAdES signature. ETSI ETSI TS 119 442 V1.1.1 (2019-02) 19 Table 2 shows the cardinalities of the components required in this protocol for incorporating signature(s), for requesting the validation of AdES signatures, depending on its types (CAdES, PAdES or XAdES) and their relative position with respect the signed document(s). Rows in the table show information corresponding to the different types of AdES signatures whose validation is requested, as well as their relative position to the signed document(s). The first column shows the different types of AdES signatures that can be submitted to the server. Column I shows the cardinalities of the signature object container. Colum II shows the contents of the signature object container. The values appearing in the cells of this column may be the following ones: • Signature: This value indicates that the signature object container contains the non-embedded signature itself. • Reference: This content appears when submitting an embedded signature. It indicates that the signature object container shall contain a reference to the embedded signature. Column III shows the cardinalities of the input documents container that includes either a document embedding the signature or a reference to an underlying protocol attachment that contains the document embedding the signature. Each cell in I and III columns indicates the required cardinality of the component shown in the header of the corresponding column, for the type of signature, located in a relative position to the signed document(s) as indicated in the header of the corresponding row. An integer value indicates an exact number of components, "*" stands for "0 or more", and "0..1" means "0 or 1". Table 2: Placement of signatures Component Type of signature I Signature object container II Contents of signature object container III Input documents container containing embedded signatures or references to attachments with signatures CMS structure attached 1 Signature 0 CMS structure detached 1 Signature 0 Non-embedded XAdES 1 Signature 0 Embedded XAdES 0..1 Reference 1 PAdES enveloped within the PDF document (embedded signature) 0..1 Reference 1 NOTE: Within one CMS structure there are as many CAdES signatures as items within the signerInfos component.

5.1.3.1 Components semantics
|
The protocol shall allow including the signed document in several containers depending on its relative position regarding the signature that signs it: 1) If a non-embedded signature envelops the document, then the client shall place the enveloping signature and the enveloped signed document within the signature object container. 2) If the signature is not as in item 1), then the client shall place the signed document either directly within the input documents container or within an underlying protocol attachment. Additionally, the input documents container shall contain one sub-component containing either the document or a reference to the attachment where the document is placed. The current protocol shall also allow submitting to the server other representations of the signed documents different than the actual documents. Each type of representation shall be placed in a different sub-component of the input documents container, as indicated below: a) If a client wants to submit the digest of the actual signed document, then the client shall place this digest within the document digest container. b) If a client wants to submit the result of transforming a document, it shall place this transformed document either: - within the transformed document container; OR - within an underlying transport protocol attachment. In this case, the transformed document container shall include a reference to this attachment. Table 3 shows the cardinalities of the components required in this protocol for incorporating signed documents, or signed documents representations (transformed documents and documents digests) for requesting the validation of AdES signatures, depending on the types of the signatures and their relative position with the signed document(s). Rows in the table show information corresponding to the different types of AdES signatures whose validation is requested, as well as their relative position to the signed document(s). The first column shows the different types of AdES signatures that can be submitted to the server. Column Document container shows the cardinalities of the document container. Column Transformed document container shows the cardinalities of transformed document container. Column Document digest container shows the cardinalities of document digest container. The conventions used in Table 3 for indicating cardinalities are the same as the conventions used in Table 2. ETSI ETSI TS 119 442 V1.1.1 (2019-02) 21 Table 3: Components containing either documents or representations of documents in validation requests messages Component and subcomponents Type of signature Input documents container containing documents or documents representations Document container Transformed document container Document digest container CMS structure attached 0 0 0 CMS structure detached 0..1 0 0..1 Non-embedded XAdES * * * Embedded XAdES 1..* * * PAdES enveloped within the PDF document 0..1 0 0..1 NOTE 1: In the case of embedded XAdES document container has a minimum cardinality of 1, as it is the only way of submitting to the server the embedded signature: within the signed document that embeds it. If the signature is not embedded, then either the document or a representation of the document can be submitted as the signature is submitted within the signature object container. NOTE 2: The protocols defined in the present document allow sending either one PDF document enclosing one or more PAdES signatures, or one PAdES signature detached from any PDF document and the digest of the document, understood as specified in clause 3.4. As that clause mentioned, details on how to compute the digest for each signature of this type, can be found in ISO 32000-1 [i.8].

The following children elements of dss2:OptionalInputsVerifyType type shall not be present: 1) The dss2:AddTimeStamp element. 2) The dss2:ReturnAugmentedSignature element. 3) The dss2:ReturnTimeStampedSignature element. 4) The dss2:ReturnProcessingDetails element. 5) The dsb:Other element. ETSI ETSI TS 119 442 V1.1.1 (2019-02) 26 NOTE 1: The three first elements in the former list are not allowed because this protocol supports validation, but not augmentation. The dss2:ReturnProcessingDetails element is not allowed because clients desiring to get detailed information on the validation process can request signed or unsigned validation report(s) using the etsival:ReturnValidationReport element. The dsb:Other element is not allowed for keeping a low degree of optionality. In addition to that, the etsival:ReturnAugmentedSignature and etsival:TSTokensQualityLevel elements shall not be present either. NOTE 2: The optional child element etsival:ReturnAugmentedSignature is the component for requesting augmenting of the signature. The protocol specified in this clause is the "validation protocol". The etsival:TSTokensQualityLevel requests to the server that it uses time-stamp tokens of a certain quality level during the augmentation process, if it requires them. They will certainly be used within the "augmentation protocol" and the "validation and augmentation protocol". These elements are present in the redefinition of the dss2:OptionalInputsVerifyType type for re-using this XML schema definition in the "validation and augmentation" protocol.

5.1.4.2 New components defined in the present document
|
5.1.4.2.1 Component for identifying the signatures to be processed (signatures-to-process- refs container) 5.1.4.2.1.1 Introduction A validation request message may contain more than one signature; however, certain business processes may not require all of them to be processed. Consequently, requests messages need a mechanism for allowing the client to enumerate to the server the signatures that the client requests to process (validate in the case of this validation protocol, augment in the case of the augmentation protocol, or validate and augment in the validation and augmentation protocol). This mechanism is provided by the optional input that is fully specified in clause. 5.1.4.2.1.2 Component semantics The signatures-to-process-refs component shall contain one reference per signature that the server is requested to process. The signatures-to-process-refs component shall allow referencing any signature present in the validation request. There are are three different ways for building a reference to one signature, namely: 1) Using the digest value of the signature computed using a specific digest algorithm. This mechanism may be used for referencing any type of signature. In this case, this component: - shall include one or more digest values (each one computed on one digital signature); - shall include the identification of one digest algorithm: the algorithm used for computing all the digest values; and - shall include the identifier of a canonicalization algorithm, if some of the signatures to validate are XAdES signatures. 2) Using a pointer to the embedding document and a XPath expression pointing to that specific embedded XAdES signature within the embedding document. This mechanism may only be used if the signature is an embedded XAdES signature. 3) Using the name of the field where the PAdES signature is embedded within the PDF document. This mechanism may only be used if the signature is a PAdES signature. This component may contain references based on different referencing mechanisms if they are references to different signatures. This component shall contain only one reference for one signature. 5.1.4.2.1.3 XML component The ProcessSignatures optional input shall be an instance of SignatureIdentifiersType defined as in XML Schema file "19442xmlSchema.xsd", whose location is detailed in clause A.1, and is copied below for information. <!—targetNamespace=http://uri.etsi.org/19442/v1.1.1# --> <xs:element name="ProcessSignatures" type="etsival:SignaturesReferencesType"/> <xs:complexType name="SignaturesReferencesType"> <xs:sequence> <xs:element ref="etsival:DigestReferences" minOccurs="0"/> <xs:element ref="etsivr:XAdESSignaturePtr" minOccurs="0" maxOccurs="unbounded"/> <xs:element name="PAdESFieldName" type="xs:string" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:element name="DigestReferences" type="etsival:DigestReferencesType"/> <xs:complexType name="DigestReferencesType"> <xs:sequence> <xs:element name="CanonicalizationMethod" type="xs:anyURI" minOccurs="0"/> ETSI ETSI TS 119 442 V1.1.1 (2019-02) 28 <xs:element name="DigestMethod" type="xs:anyURI"/> <xs:element name="DigestValue" type="xs:base64Binary" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> This XML Schema piece references etsivr:XAdESSignaturePtr element, which is defined in ETSI TS 119 102-2 [11]. For the sake of completeness of the present document, below follows its definition, copied from the XML Schema of ETSI TS 119 102-2 [11]. <!—targetNamespace=http://uri.etsi.org/19102/v1.2.1# --> <xs:element name="XAdESSignaturePtr" type="etsivr:XAdESSignaturePtrType"/> <xs:complexType name="XAdESSignaturePtrType"> <xs:sequence> <xs:element name="NsPrefixMapping" type="etsivr:NsPrefixMappingType" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> <xs:attribute name="WhichDocument" type="xs:IDREF" use="optional"/> <xs:attribute name="XPath" type="xs:string" use="optional"/> <xs:attribute name="SchemaRefs" type="xs:IDREFS" use="optional"/> </xs:complexType> <xs:complexType name="NsPrefixMappingType"> <xs:sequence> <xs:element name="NamespaceURI" type="xs:anyURI"/> <xs:element name="NamespacePrefix" type="xs:string"/> </xs:sequence> </xs:complexType> The DigestReferences child element may be used for referencing any type of signature within the request. The value of the CanonicalizationMethod child element shall be an URI identifying a canonicalization algorithm. The value of the DigestMethod child element shall be an URI identifying a digest algorithm. The value of the DigestValue child element shall be the base-64 encoded value of the digest of the referenced digital signature computed using the digest algorithm identified in DigestMethod child element's value. The actual computation of the digest value shall be dependent on the type of signature and shall be performed as follows: 1) In case of CAdES signatures, the input to the digest value computation shall be one of the DER-encoded instances of SignedInfo type present within the CMS structure. NOTE: A CMS structure can enclose several parallel CAdES signatures (each item in the signerInfos array, which is an instance of SignedInfo type, contains the digital signature value generated by a different private key). 2) In case of XAdES signatures, the input of the digest value computation shall be the result of applying the canonicalization algorithm identified within the CanonicalizationMethod child element's value to the corresponding ds:Signature element and its contents. The canonicalization shall be computed keeping this ds:Signature element as a descendant of the XML root element, without detaching it. 3) In case of PAdES signatures, the input of the digest value computation shall be the result of decoding the hexadecimal string present within the Contents field of the Signature PDF dictionary enclosing one PAdES digital signature. XAdESSignaturePtr child element shall only be used for referencing XAdES signatures.

The xadesSigPtrs element may only be used for referencing XAdES signatures. The xadesSigPtrs element is an array of objects instance of dss2-SignaturePtrType specified in clause 4.2.9.1 of DSS-X core v2.0 [1], with the following exception: 1) The element whichDoc may be absent. If this element is present, its value shall be as specified in clause 4.2.9.1 of DSS-X core v2.0 [1] and the corresponding item of the array shall reference a signature embedded in some input document. If this element is absent, the corresponding item of the array shall reference one of the signatures placed within the signature object container. The pAdESFieldNames array may only be used for referencing PAdES signatures. The value of each item within the pAdESFieldNames array shall be the name of the PDF field where the referenced PAdES signature is present within the PDF signed document.

5.2.3.2.3 Component for notifying the signature policy applied during the validation
|
5.2.3.2.3.1 Component semantics This component shall provide means for returning to the client the identifier of the signature validation policy applied by the server for validating the signature(s). This component shall appear in the response to requests of validation of digital signatures that incorporate the component requesting the server to validate the signature(s) using a certain signature validation policy, specified in clause 5.1.4.2.2.1 of the present document, if the server has been able to check all the constraints defined in the signature validation policy identified in the present component, on all the validated signatures. It may also appear in responses to requests that do not incorporate the aforementioned component. 5.2.3.2.3.2 XML component The element that shall notify to the client the signature validation policy against which the signature has been validated shall be the AppliedSignatureValidationPolicy element. The AppliedSignatureValidationPolicy element shall be defined as in XML Schema file "19442xmlSchema.xsd", whose location is detailed in clause A.1, and is copied below for information. <!—targetNamespace="http://uri.etsi.org/19442/v1.1.1#" --> <xs:element name="AppliedSignatureValidationPolicy" type="xs:anyURI"/> The AppliedSignatureValidationPolicy element shall be a direct child of the dss2:OptionalOutputs optional child of dss2:VerifyResponse. NOTE: When a dss2:VerifyRequest includes the UseSignatureValidationPolicy optional input, it is instructing the server to use the same signature validation policy for validating all the signatures whose validation is requested. The server applies the same signature validation policy for all the signatures whose validation is requested. Consequently one single instance of AppliedSignatureValidationPolicy is enough to notify its identifier, and this value is always placed out of all the ResultsForOneSignature children. ETSI ETSI TS 119 442 V1.1.1 (2019-02) 44 The AppliedSignatureValidationPolicy element shall have as value the unique identifier of the signature validation policy used by the server for validating the signature as an URI.

The value of this element shall be the unique identifier of the signature validation policy used by the server for validating the signature as an URI. If the identifier of the signature validation policy is an OID, then the value of this element shall be an URN indicating the value of the aforementioned OID as specified in IETF RFC 3061 [14]. 5.2.3.2.4 Component for notifying the signature policies under which the server can conduct validation 5.2.3.2.4.1 Component semantics This component shall provide means for returning to the client the identifiers of the signature validation policies under which the server can validate signatures. This component shall appear in the response to requests of validation of digital signatures that incorporate the component requesting the server to validate the signature(s) using a certain signature validation policy, specified in clause 5.1.4.2.2.1 of the present document. This component shall only appear if the server is not able to validate the signature under the signature validation policy requested by the client in the aforementioned component of the validation request. 5.2.3.2.4.2 XML component The element that shall notify to the client the signature validation policies under which the server can conduct validation of digital signatures shall be the AvailableSignatureValidationPolicies element. The AvailableSignatureValidationPolicies element shall be defined as in XML Schema file "19442xmlSchema.xsd", whose location is detailed in clause A.1, and is copied below for information. <!—targetNamespace="http://uri.etsi.org/19442/v1.1.1#" <xs:element name="AvailableSignatureValidationPolicies" type="AvailableSignatureValidationPoliciesType"/> <xs:complexType name="AvailableSignatureValidationPoliciesType"> <xs:sequence> <xs:element name="AvailableSignatureValidationPolicyID" type="xs:anyURI" minOccurs="1" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> The AvailableSignatureValidationPolicies element shall be a direct child of the dss2:OptionalOutputs optional child of dss2:VerifyResponse. NOTE: The information of the signature validation policies against which the server may validate signatures is independent of the validated signatures. Consequently one single instance of AvailableSignatureValidationPolicies is enough to notify its identifier, and this value is always placed outside of all the ResultsForOneSignature children. Each AvailableSignatureValidationPolicyID child element shall have as value the unique identifier of one signature validation policy against which the server is able to validate digital signatures, as an URI. If the identifier of the signature validation policy is an OID, then the value of this element shall be an URN indicating the value of the aforementioned OID as specified in IETF RFC 3061 [14]. ETSI ETSI TS 119 442 V1.1.1 (2019-02) 45 5.2.3.2.4.3 JSON component In the JSON protocol derived from OASIS specifications the element that shall notify to the client the signature validation policies under which the server can conduct validation of digital signatures shall be the availableSigValPols element. Each item of the array shall have as value the unique identifier of one signature validation policy against which the server is able to validate digital signatures, as an URI. If the identifier of the signature validation policy is an OID, then the value of this element shall be an URN indicating the value of the aforementioned OID as specified in IETF RFC 3061 [14].

5.2.3.2.5.1 Component semantics This component shall contain either the signed or the unsigned detailed validation report for one or more digital signatures that the server has validated in response to one request that requested its generation (incorporating the component specified in clause 5.1.4.2.3 of the present document). If this element is child of the signature processing results container it shall contain the validation report of one signature (the one that the signature processing results container provides details of). If this element is child of the optional outputs component, it may contain the validation report on more than one signatures. Clause 8.4.3.3 provides details on what the server may decide regarding the generation of this component when building the validation response message. When the validation report is used for reporting on the validation of more than one signature, its contents shall contain mechanisms for identifying each one of the validated and reported signatures. NOTE: The format defined in ETSI TS 119 102-2 [11] for the validation report allows reporting on the validation of several signatures and includes mechanisms for identifying the reported signatures. 5.2.3.2.5.2 XML component The element that shall contain the detailed validation report for one or more digital signatures shall be the ValidationReport, which shall be an instance of etsival:ValidationReportContainerType defined as in XML Schema file "19442xmlSchema.xsd", whose location is detailed in clause A.1, and is copied below for information. <!—targetNamespace=http://uri.etsi.org/19442/v1.1.1# --> <xs:element name="ValidationReport" type="etsival:ValidationReportContainerType"/> <xs:complexType name="ValidationReportContainerType"> <xs:choice> <xs:element name="ETSITS11910202XMLReport" type="etsivr:ValidationReportType" minOccurs="0"/> <xs:element name="other" type="xs:base64Binary" minOccurs="0"/> </xs:choice> <xs:attribute name="isSigned" type="xs:boolean" use="required"/> <xs:attribute name="Encoding" type="xs:string" use="optional"/> <xs:attribute name="SpecificationId" type="xs:anyURI" use="optional"/> </xs:complexType> The ETSITS11910202XMLReport element shall contain an instance of the XML validation report specified in ETSI TS 119 102-2 [11].

The signature augmentation request message shall allow requesting to the server the augmentation of one or more AdES signatures. The request message shall be able to submit the signatures to be augmented, following the same principles as in the validation request message, either: 1) within the signature object container (if the signature is a non-embedded signature); or 2) within the input documents container (if the signature is an embedded signature); or 3) within an underlying protocol attachment (if the signature is an embedded signature), in which case this attachment shall be referenced within the input documents container. The request message shall not include neither transformed documents nor digests of signed documents. The request message may incorporate documents. The request message shall include a set of additional input components for detailing what is actually requested to the server. The request message shall allow to request augmenting different signatures to the same level. It shall not support requesting to augment different signatures to different levels. The request message may contain a component whose value is an identifier of the message itself. The augmentation request message shall contain one or more components identifying protocols and/or profiles that the response message is compliant with. The first one of such components shall have the following URI as value, identifying the response as one that has been built using the "augmentation" protocol specified in the present document: • http://uri.etsi.org/19442/v1.1.1/augmentationprotocol#.

6.2.1.1 Component semantics
|
The signature augmentation response message shall allow the server to return to the client one or more AdES signatures, which shall be the result of augmenting the AdES signatures submitted by the client to the requested level. The signature augmentation response message shall have one or more signature result containers for returning either: 1) the augmented signature; or 2) an indication of error while trying to augment the signature and a reference to the non augmented signature. The response message shall be able to return the augmented signatures either: 1) within the signature object container (if the signature is a non-embedded signature); or 2) within the document with signature container (if the signature is an embedded signature); or 3) within an underlying protocol attachment (if the signature is an embedded signature), in which case this attachment shall be referenced within the document with signature container. NOTE: In essence, an augmentation response message needs to submit only the augmented AdES signatures. However, if these are embedded signatures, the message can submit the signed document(s) with the embedded signatures. This message shall contain one or more components identifying protocols and/or profiles that the response message is compliant with. The first one of such components shall have the following URI as value, identifying the response as one that has been built using the augmentation protocol specified in the present document: • http://uri.etsi.org/19442/v1.1.1/augmentationprotocol# This message may contain a component whose value is an identifier of the message itself. This message may contain component whose value is the identifier of the request message that this message is the response of.
