ETSI TS 119 144-5 V1.1.1 (2016-06)

Electronic Signatures and Infrastructures (ESI); PAdES digital signatures - Testing Conformance and Interoperability; Part 5: Testing Conformance of additional PAdES signatures

This multi-part deliverable provides technical specifications for helping  implementers and accelerating the development of PAdES signature creation and validation applications. The test results may also be used in conformity assessment for signature creation and validation applications (EN 19 103) with policies requiring conformity to PAdES formats and procedures. First, it will define test suites as completely as possible for supporting the organization of interoperability testing events where different PAdES related applications may check their actual interoperability. Additionally, it will include the specifications required for building up software tools for actually testing technical compliance of PAdES signatures against the relevant PAdES related technical specifications. This part 5 will specify, among other things, rules for testing compliance of signatures against the PAdES Baseline Profile specification. It will allow developing a tool that could automatically check that a PAdES Baseline signature is fully compliant with the relevant part of EN 319 142, without claiming any statement on their validity or not.

Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Electronic Signatures and
Infrastructures (ESI).
The present document is part 5 of a multi-part deliverable covering PAdES digital signatures - Testing Conformance
and Interoperability. Full details of the entire series can be found in part 1 [i.1].
A tool implementing the present document has been developed and is accessible at http://signatures-conformance-
checker.etsi.org/.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document defines the set of checks to be performed for testing conformance of PAdES signatures against
additional PAdES signatures profiles as specified in ETSI EN 319 142-2 [3]. It defines only the checks that are specific
to additional PAdES signatures. The set of checks that are common to both additional and baseline PAdES signatures,
are defined in ETSI TS 119 144-4 [6].
The complete set of checks to be performed by any tool on additional PAdES signatures is the union of the sets defined
within the present document and the set of common checks for testing conformance against ETSI EN 319 142-1 [1] and
ETSI EN 319 142-2 [3] defined in ETSI TS 119 144-4 [6], as indicated in the normative clauses of the present
document.
The present document does not specify checks leading to conclude whether a signature is technically valid or not (for
instance, it does not specify checks for determining whether the cryptographic material present in the signature may be
considered valid or not). In consequence, no conclusion may be inferred regarding the technical validity of a signature
that has been successfully tested by any tool conformant to the present document.
Checks specified by the present document are exclusively constrained to elements specified by PAdES [1].
Regarding PAdES attributes, the present document explicitly differentiates between structural requirements that are
defined on building blocks, and the requirements specified for additional PAdES signatures conformance.
The present document is intentionally not linked to any software development technology and is also intentionally
agnostic on implementation strategies. This is one of the reasons why the test assertions set specified in the present
document includes tests on the correctness of the structure of all the elements specified by PAdES [1].

4 Overview
The present clause describes the main aspects of the technical approach used for specifying the set of checks to be
performed for testing conformance to ETSI EN 319 142-2 [3].
ETSI EN 319 142-1 [1] defines requirements for building blocks and PAdES baseline signatures. For the purpose of
identifying the whole set of test assertions required for testing conformance against additional PAdES signatures as
specified in ETSI EN 319 142-2 [3], the present document classifies the whole set of requirements specified in ETSI
EN 319 142-1 [1] and in ETSI EN 319 142-2 [3] in two groups as follows:
1) Requirements "PAdES_BB" (after "PAdES building blocks"): requirements defined in clause 4, clause 5,
clause 6 of ETSI EN 319 142-1 [1] to be satisfied by both PAdES baseline signatures as specified in ETSI
EN 319 142-1 [1] and additional PAdES signatures as specified in ETSI EN 319 142-2 [3]. The checks for
these requirements are defined in ETSI TS 119 144-4 [6]. When needed in the present document, such checks
are referred by their TA_id.
2) Requirements "PAdES_AS" (after "Additional PAdES signatures"): requirements defined in clauses 4, 5 and 6
of ETSI EN 319 142-2 [3]. These
