ETSI ETSI EN 319 132-2 V1.1.1 (2016-04) 6 1 Scope The present document specifies XAdES digital signatures. XAdES signatures are built on XML digital signatures [i.4], by incorporation of signed and unsigned qualifying properties, which fulfil certain common requirements (such as the long term validity of digital signatures, for instance) in a number of use cases. The present document specifies a number of XAdES signature levels, addressing incremental requirements to maintain the validity of the signatures over the long term, in a way that a certain level always addresses all the requirements addressed at levels that are below it. These XAdES extended signatures offer a higher degree of optionality than the XAdES baseline signatures specified ETSI EN 319 132-1 [1]. Procedures for creation, augmentation, and validation of XAdES digital signatures are out of scope and specified in ETSI EN 319 102-1 [i.7]. Guidance on creation, augmentation and validation of XAdES digital signatures is provided including the usage of the different properties is provided in ETSI TR 119 100 [i.6]. The present document aims at supporting electronic signatures in different regulatory frameworks. NOTE: Specifically but not exclusively, XAdES digital signatures specified in the present document aim at supporting electronic signatures, advanced electronic signatures, qualified electronic signatures, electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU) No 910/2014 [i.1]. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

The present document uses the term "element" exclusively for denoting XML elements. The present document uses the terms "container" or "element" for denoting XML elements that are containers of qualifying properties (for instance QualifyingProperties, SignedProperties, or UnsignedProperties). The present document uses the term "attribute" exclusively for denoting XML attributes of XML elements. Consequently, a qualifying property, being a XML element, can have (XML) attributes. The present document uses the term "child element" exclusively in the context of XML content, for denoting an XML element that is a child element of another XML element. SIST EN 319 132-2 V1.1.1:2016
ETSI ETSI EN 319 132-2 V1.1.1 (2016-04) 8 4 Additional XAdES levels without references to validation data 4.1 Overview The present document specifies a number of additional levels for XAdES. Each level is generated by a different combination of the XAdES qualifying properties specified in ETSI EN 319 132-1 [1], and incorporated to the XAdES signatures using one of the two mechanisms (direct or indirect incorporation) described in clause 4.4 of ETSI EN 319 132-1 [1]. NOTE 1: ETSI TR 119 100 [i.6] provides a description on the life-cycle of a signature and the rationales on which level is suitable in which situation. NOTE 2: Clause 4.3 defines four XAdES levels namely the XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and XAdES-E-A built on XAdES-E-T. Normative Annex A defines levels of XAdES signatures incorporating qualifying properties that encapsulate references to validation data and qualifying properties that encapsulate time-stamp tokens on them. NOTE 3: Names of XML elements in the namespace whose URI is http://www.w3.org/2000/09/xmldsig# will be preceded in the present document by prefix ds. No other prefixes will be used in the present document for identifying XAdES containers and/or XAdES qualifying properties, as their usage is not required for unambiguously identifying the referenced XAdES container or XAdES qualifying property, regardless of the namespace where they have been defined. NOTE 4: The requirements on the presence and cardinality of the attributes for each XAdES signature level are expressed in tables whose formats and semantics are as specified in clause 6.2.2 of ETSI EN 319 132-1 [1]. 4.2 General requirements XAdES qualifying properties deprecated by ETSI EN 319 132-1 [1] (see Annex D) do not appear in the tables. Their cardinality shall be 0 and consequently, they shall not be incorporated in the signature. Any XAdES signature of any of the levels specified in the present document shall contain at least one of the following components with the specified contents: • The SigningCertificateV2 signed qualifying property. • The ds:KeyInfo element. If the SigningCertificateV2 qualifying property is incorporated to the signature, no restrictions apply to this element. Otherwise, then the following restrictions apply: - the ds:KeyInfo element shall include a ds:X509Data containing the signing certificate; - the ds:KeyInfo element may also contain other certificates; - the ds:SignedInfo element shall contain a ds:Reference element that ensures that the signing certificate is actually signed. NOTE 1: Signing the whole ds:KeyInfo locks the element: any addition of a certificate or validation data would make signature validation fail. Applications can, alternatively, use XPath transforms for signing at least the signing certificate, leaving the ds:KeyInfo element open for addition of new data after signing. The algorithms and key lengths used to generate and augment digital signatures should be as specified in ETSI TS 119 312 [i.8]. NOTE 2: Cryptographic suites recommendations defined in ETSI TS 119 312 [i.8] can be superseded by national recommendations. NOTE 3: IETF RFC 6931 [i.9]defines a set of additional XML security URIs, which complement those ones defined in XMLDSIG [i.4]. SIST EN 319 132-2 V1.1.1:2016
ETSI ETSI EN 319 132-2 V1.1.1 (2016-04) 9 4.3 XAdES-E-BES, XAdES-E-EPES, XAdES-E-T signatures, and XAdES-E-A signatures built on XAdES-E-T signatures XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and XAdES-E-A built on XAdES-E-T signatures shall be XAdES signatures whose qualifying properties satisfy the requirements specified in the present clause. XAdES-E-EPES signatures are built on XAdES-E-BES signatures by adding one SignaturePolicyIdentifier qualifying property. XAdES-E-T signatures are built on XAdES-E-BES and XAdES-E-EPES signatures by adding one or more SignatureTimeStamp qualifying properties. XAdES-E-A signatures are built on XAdES-E-T, XAdES-E-C, XAdES-E-X (of Type 1 and of Type 2), XAdES-E-X-Long, and XAdES-E-X-L (of Type 1 and of Type 2) signatures. Annex A specifies XAdES-E-C, XAdES-E-X (of Type 1 and of Type 2), XAdES-E-X-Long, and XAdES-E-X-L (of Type 1 and of Type 2) signatures, and XAdES-E-A signatures built on them.

The present document specifies XAdES digital signatures. XAdES signatures are built on XML digital signatures [i.4],
by incorporation of signed and unsigned qualifying properties, which fulfil certain common requirements (such as the
long term validity of digital signatures, for instance) in a number of use cases.
The present document specifies a number of XAdES signature levels, addressing incremental requirements to maintain
the validity of the signatures over the long term, in a way that a certain level always addresses all the requirements
addressed at levels that are below it. These XAdES extended signatures offer a higher degree of optionality than the
XAdES baseline signatures specified ETSI EN 319 132-1 [1].
Procedures for creation, augmentation, and validation of XAdES digital signatures are out of scope and specified in
ETSI EN 319 102-1 [i.7]. Guidance on creation, augmentation and validation of XAdES digital signatures is provided
including the usage of the different properties is provided in ETSI TR 119 100 [i.6].
The present document aims at supporting electronic signatures in different regulatory frameworks.
NOTE: Specifically but not exclusively, XAdES digital signatures specified in the present document aim at
supporting electronic signatures, advanced electronic signatures, qualified electronic signatures,
electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU)
No 910/2014 [i.1].

4 Additional XAdES levels without references to
validation data
4.1 Overview
The present document specifies a number of additional levels for XAdES.
Each level is generated by a different combination of the XAdES qualifying properties specified in ETSI
EN 319 132-1 [1], and incorporated to the XAdES signatures using one of the two mechanisms (direct or indirect
incorporation) described in clause 4.4 of ETSI EN 319 132-1 [1].
NOTE 1: ETSI TR 119 100 [i.6] provides a description on the life-cycle of a signature and the rationales on which
level is suitable in which situation.
NOTE 2: Clause 4.3 defines four XAdES levels namely the XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and
XAdES-E-A built on XAdES-E-T. Normative Annex A defines levels of XAdES signatures incorporating
qualifying properties that encapsulate references to validation data and qualifying properties that
encapsulate time-stamp tokens on them.
NOTE 3: Names of XML elements in the namespace whose URI is http://www.w3.org/2000/09/xmldsig# will be
preceded in the present document by prefix ds. No other prefixes will be used in the present document
for identifying XAdES containers and/or XAdES qualifying properties, as their usage is not required for
unambiguously identifying the referenced XAdES container or XAdES qualifying property, regardless of
the namespace where they have been defined.
NOTE 4: The requirements on the presence and cardinality of the attributes for each XAdES signature level are
expressed in tables whose formats and semantics are as specified in clause 6.2.2 of ETSI
EN 319 132-1 [1].
4.2 General requirements
XAdES qualifying properties deprecated by ETSI EN 319 132-1 [1] (see Annex D) do not appear in the tables. Their
cardinality shall be 0 and consequently, they shall not be incorporated in the signature.
Any XAdES signature of any of the levels specified in the present document shall contain at least one of the following
components with the specified contents:
• The SigningCertificateV2 signed qualifying property.
• The ds:KeyInfo element. If the SigningCertificateV2 qualifying property is incorporated to the
signature, no restrictions apply to this element. Otherwise, then the following restrictions apply:
- the ds:KeyInfo element shall include a ds:X509Data containing the signing certificate;
- the ds:KeyInfo element may also contain other certificates;
- the ds:SignedInfo element shall contain a ds:Reference element that ensures that the signing
certificate is actually signed.
NOTE 1: Signing the whole ds:KeyInfo locks the element: any addition of a certificate or validation data would
make signature validation fail. Applications can, alternatively, use XPath transforms for signing at least
the signing certificate, leaving the ds:KeyInfo element open for addition of new data after signing.
The algorithms and key lengths used to generate and augment digital signatures should be as specified in ETSI
TS 119 312 [i.8].
NOTE 2: Cryptographic suites recommendations defined in ETSI TS 119 312 [i.8] can be superseded by national
recommendations.
NOTE 3: IETF RFC 6931 [i.9]defines a set of additional XML security URIs, which complement those ones
defined in XMLDSIG [i.4].

4.3 XAdES-E-BES, XAdES-E-EPES, XAdES-E-T signatures,
and XAdES-E-A signatures built on XAdES-E-T signatures
XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and XAdES-E-A built on XAdES-E-T signatures shall be XAdES
signatures whose qualifying properties satisfy the requirements specified in the present clause.
XAdES-E-EPES signatures are built on XAdES-E-BES signatures by adding one SignaturePolicyIdentifier
qualifying property.
XAdES-E-T signatures are built on XAdES-E-BES and XAdES-E-EPES signatures by adding one or more
SignatureTimeStamp qualifying properties.
XAdES-E-A signatures are built on XAdES-E-T, XAdES-E-C, XAdES-E-X (of Type 1 and of Type 2), XAdES-E-X-
Long, and XAdES-E-X-L (of Type 1 and of Type 2) signatures.
Annex A specifies XAdES-E-C, XAdES-E-X (of Type 1 and of Type 2), XAdES-E-X-Long, and XAdES-E-X-L (of
Type 1 and of Type 2) signatures, and XAdES-E-A signatures built on them.

Introduction
Electronic commerce has emerged as a frequent way of doing business between companies across local, wide area and
global networks. Trust in this way of doing business is essential for the success and continued development of
electronic commerce. It is therefore important that companies using this electronic means of doing business have
suitable security controls and mechanisms in place to protect their transactions and to ensure trust and confidence with
their business partners. In this respect digital signatures are an important security component that can be used to protect
information and provide trust in electronic business.
The present document is intended to cover digital signatures supported by PKI and public key certificates, and aims to
meet the general requirements of the international community to provide trust and confidence in electronic transactions,
including, amongst other, applicable requirements from Regulation (EU) No 910/2014 [i.1].
The present document can be used for any transaction between an individual and a company, between two companies,
between an individual and a governmental body, etc. The present document is independent of any environment. It can
be applied to any environment e.g. smart cards, GSM SIM cards, special programs for electronic signatures, etc.
The present document is part of a rationalized framework of standards (see ETSI TR 119 000 [i.5]). See ETSI
TR 119 100 [i.6] for getting guidance on how to use the present document within the aforementioned framework.

4 Additional XAdES levels without references to
validation data
4.1 Overview
The present document specifies a number of additional levels for XAdES.
Each level is generated by a different combination of the XAdES qualifying properties specified in ETSI
EN 319 132-1 [1], and incorporated to the XAdES signatures using one of the two mechanisms (direct or indirect
incorporation) described in clause 4.4 of ETSI EN 319 132-1 [1].
NOTE 1: ETSI TR 119 100 [i.6] provides a description on the life-cycle of a signature and the rationales on which
level is suitable in which situation.
NOTE 2: Clause 4.3 defines four XAdES levels namely the XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and
XAdES-E-A built on XAdES-E-T. Normative Annex A defines levels of XAdES signatures incorporating
qualifying properties that encapsulate references to validation data and qualifying properties that
encapsulate time-stamp tokens on them.
NOTE 3: Names of XML elements in the namespace whose URI is http://www.w3.org/2000/09/xmldsig# will be
preceded in the present document by prefix ds. No other prefixes will be used in the present document
for identifying XAdES containers and/or XAdES qualifying properties, as their usage is not required for
unambiguously identifying the referenced XAdES container or XAdES qualifying property, regardless of
the namespace where they have been defined.
NOTE 4: The requirements on the presence and cardinality of the attributes for each XAdES signature level are
expressed in tables whose formats and semantics are as specified in clause 6.2.2 of ETSI
EN 319 132-1 [1].
4.2 General requirements
XAdES qualifying properties deprecated by ETSI EN 319 132-1 [1] (see Annex D) do not appear in the tables. Their
cardinality shall be 0 and consequently, they shall not be incorporated in the signature.
Any XAdES signature of any of the levels specified in the present document shall contain at least one of the following
components with the specified contents:
• The SigningCertificateV2 signed qualifying property.
• The ds:KeyInfo element. If the SigningCertificateV2 qualifying property is incorporated to the
signature, no restrictions apply to this element. Otherwise, then the following restrictions apply:
- the ds:KeyInfo element shall include a ds:X509Data containing the signing certificate;
- the ds:KeyInfo element may also contain other certificates;
- the ds:SignedInfo element shall contain a ds:Reference element that ensures that the signing
certificate is actually signed.
NOTE 1: Signing the whole ds:KeyInfo locks the element: any addition of a certificate or validation data would
make signature validation fail. Applications can, alternatively, use XPath transforms for signing at least
the signing certificate, leaving the ds:KeyInfo element open for addition of new data after signing.
The algorithms and key lengths used to generate and augment digital signatures should be as specified in ETSI
TS 119 312 [i.8].
NOTE 2: Cryptographic suites recommendations defined in ETSI TS 119 312 [i.8] can be superseded by national
recommendations.
NOTE 3: IETF RFC 6931 [i.9]defines a set of additional XML security URIs, which complement those ones
defined in XMLDSIG [i.4].

Introduction
Electronic commerce has emerged as a frequent way of doing business between companies across local, wide area and
global networks. Trust in this way of doing business is essential for the success and continued development of
electronic commerce. It is therefore important that companies using this electronic means of doing business have
suitable security controls and mechanisms in place to protect their transactions and to ensure trust and confidence with
their business partners. In this respect digital signatures are an important security component that can be used to protect
information and provide trust in electronic business.
The present document is intended to cover digital signatures supported by PKI and public key certificates, and aims to
meet the general requirements of the international community to provide trust and confidence in electronic transactions,
including, amongst other, applicable requirements from Regulation (EU) No 910/2014 [i.1].
The present document can be used for any transaction between an individual and a company, between two companies,
between an individual and a governmental body, etc. The present document is independent of any environment. It can
be applied to any environment e.g. smart cards, GSM SIM cards, special programs for electronic signatures, etc.
The present document is part of a rationalized framework of standards (see ETSI TR 119 000 [i.5]). See
ETSI TR 119 100 [i.6] for getting guidance on how to use the present document within the aforementioned framework.

5 Draft ETSI EN 319 132-2 V1.0.0 (2015-06)
1 Scope
The present document specifies XAdES digital signatures. XAdES signatures are built on XML digital signatures [i.4],
by incorporation of signed and unsigned qualifying properties, which fulfil certain common requirements (such as the
long term validity of digital signatures, for instance) in a number of use cases.
The present document specifies a number of XAdES signature levels, addressing incremental requirements to maintain
the validity of the signatures over the long term, in a way that a certain level always addresses all the requirements
addressed at levels that are below it. These XAdES extended signatures offer a higher degree of optionality than the
XAdES baseline signatures specified ETSI EN 319 132-1 [1].
The present document aims at supporting electronic signatures in different regulatory frameworks.
NOTE: Specifically but not exclusively, XAdES digital signatures specified in the present document aim at
supporting electronic signatures, advanced electronic signatures, qualified electronic signatures,
electronic seals, advanced electronic seals, and qualified electronic seals as per Regulation (EU)
No 910/2014 [i.1].

3 Definitions, abbreviations and terminology
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI TR 119 001 [i.2] and
ETSI EN 319 132-1 [1], apply.
3.2 Abbreviations
For the purposes of the present document, the following abbreviations apply:

3.3 Terminology
The present document uses the term "qualifying property" for denoting a XML element that qualifies the signature, the
signed data objects, or the signer.
The present document uses the term "element" exclusively for denoting XML elements.
The present document uses the terms "container" or "element" for denoting XML elements that are containers of
qualifying properties (for instance QualifyingProperties, SignedProperties, or
UnsignedProperties).
The present document uses the term "attribute" exclusively for denoting XML attributes of XML elements.
Consequently, a qualifying property, being a XML element, can have (XML) attributes.
The present document uses the term "child element" exclusively in the context of XML content, for denoting an XML
element that is a child element of another XML element.
4 Additional XAdES levels without references to
validation data
4.1 Overview
The present document specifies a number of additional levels for XAdES.
Each level is generated by a different combination of the XAdES qualifying properties specified in
ETSI EN 319 312-1 [1], and incorporated to the XAdES signatures using one of the two mechanisms (direct or indirect
incorporation) described in clause 4.4 of ETSI EN 319 312-1 [1].
NOTE 1: Clause 4.3 defines four XAdES levels namely the XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and
XAdES-E-A built on XAdES-E-T. Normative Annex A defines levels of XAdES signatures incorporating
qualifying properties that encapsulate references to validation data and qualifying properties that
encapsulate time-stamp tokens on them.

NOTE 2: Names of XML elements in the namespace whose URI is http://www.w3.org/2000/09/xmldsig# will be
preceded in the present document by prefix ds. No other prefixes will be used in the present document
for identifying XAdES containers and/or XAdES qualifying properties, as their usage is not required for
unambiguously identifying the referenced XAdES container or XAdES qualifying property, regardless of
the namespace where they have been defined.
NOTE 3: The requirements on the presence and cardinality of the attributes for each XAdES signature level are
expressed in tables whose formats and semantics are as specified in clause 6.2.2 of
ETSI EN 319 132-1 [1].
4.2 General requirements
XAdES qualifying properties obsoleted by ETSI EN 319 132-1 [1] do not appear in the tables. Their cardinality shall be
0 and consequently, they shall not be incorporated in the signature.
Any XAdES signature of any of the levels specified in the present document shall contain at least one of the following
components with the specified contents:
• The SigningCertificateV2 signed qualifying property.
• The ds:KeyInfo element. If the SigningCertificateV2 qualifying property is incorporated to the
signature, no restrictions apply to this element. Otherwise, then the following restrictions apply:
- the ds:KeyInfo element shall include a ds:X509Data containing the signing certificate;
- the ds:KeyInfo element may also contain other certificates;
- the ds:SignedInfo element shall contain a ds:Reference element that ensures that the signing
certificate is actually signed.
NOTE: Signing the whole ds:KeyInfo locks the element: any addition of a certificate or validation data would
make signature validation fail. Applications can, alternatively, use XPath transforms for signing at least
the signing certificate, leaving the ds:KeyInfo element open for addition of new data after signing.
4.3 XAdES-E-BES, XAdES-E-EPES, XAdES-E-T signatures,
and XAdES-E-A signatures built on XAdES-E-T signatures
XAdES-E-BES, XAdES-E-EPES, XAdES-E-T, and XAdES-E-A built on XAdES-E-T signatures shall be XAdES
signatures whose qualifying properties satisfy the requirements specified in the present clause.
XAdES-E-EPES signatures are built on XAdES-E-BES signatures by adding one SignaturePolicyIdentifier
qualifying property.
XAdES-E-T signatures are built on XAdES-E-BES and XAdES-E-EPES signatures by adding one or more
SignatureTimeStamp qualifying properties.
XAdES-E-A signatures are built on XAdES-E-T, XAdES-E-C, XAdES-E-X (of Type 1 and of Type 2), XAdES-E-X-
Long, and XAdES-E-X-L (of Type 1 and of Type 2) signatures.
Annex A specifies XAdES-E-C, XAdES-E-X (of Type 1 and of Type 2), XAdES-E-X-Long, and XAdES-E-X-L (of
Type 1 and of Type 2) signatures, and XAdES-E-A signatures built on them.
