Introduction
ISO/IEC 17065 [i.30] is an international standard which specifies general requirements for conformity assessment
bodies (CABs) performing certification of products, processes, or services. These requirements are not focussed on any
specific application domain where CABs work.
In ETSI EN 319 403 [1], the general requirements of [i.30] are supplemented to provide additional dedicated
requirements for CABs performing certification of trust service providers (TSPs) and the trust services they provide
towards defined criteria against which they claim conformance.
ETSI
---------------------- Page: 4 ----------------------
5 ETSI TS 119 403-3 V1.1.1 (2019-03)
ETSI EN 319 403 [1] aims to meet the general needs of the international community to provide trust and confidence in
electronic transactions including, amongst others, applicable requirements from Regulation (EU) No 910/2014 [i.1], and
from CA/Browser Forum [i.4]. It aims include support of national accreditation bodies (NABs) as specified in
Regulation (EC) No. 765/2008 [i.3] in applying ISO/IEC 17065 [i.30] for the accreditation of CABs that certify TSPs
and the trust services they provide so that this is carried out in a consistent manner. In accordance with [i.3], attestations
issued by conformity assessment bodies accredited by a NAB can be formally recognized across Europe.
ETSI EN 319 403 [1] supplements ISO/IEC 17065 [i.30] by specifying additional requirements, e.g. on resources, on
the assessment process and on the audit of a TSP's management system, as defined in ISO/IEC 17021-1 [i.6] and in
ISO/IEC 27006 [i.7].
The present document specifies supplementary requirements to those defined in [1] in order to provide additional
dedicated requirements for CABs performing certification of qualified trust service providers (QTSPs) and the qualified
trust services (QTSs) they provide towards the requirements of Regulation (EU) No 910/2014 [i.1]. It aims supporting
NABs for the accreditation of CABs in line with Article 3.18 of Regulation (EU) No 910/2014 [i.1].
The ENISA technical guidelines on trust services "Guidelines on initiation of qualified trust services" [i.9] have been
used as basis for the present document.

1 Scope
The present document defines specific supplementary requirements for the application of ETSI EN 319 403 [1] aimed at
conformity assessments (audits) of qualified trust service providers (QTSPs) and the qualified trust services (QTSs)
they provide, as well as of trust service providers, without qualified status, intending to start providing qualified trust
services, against the requirements of Regulation (EU) No 910/2014 [i.1] assuming the use of ETSI policy requirement
standards but not precluding use of other specifications.
In particular, the present document defines requirements for conformity assessment reports, including their content.

4 Requirements for CABs assessing QTSP/QTSs
against requirements of Regulation (EU)
No 910/2014
4.1 Conformity assessment scheme
CAS-4.1-01: The conformity assessment scheme for which a CAB is accredited to assess QTSP/QTSs against the
requirements of Regulation (EU) No 910/2014 [i.1] in accordance with Regulation (EC) No 765/2008 [i.3] shall be
defined in a way that such accreditation ensures the accredited CAB is competent to carry out conformity assessment of
a QTSP/QTS against the requirements of Regulation (EU) No 910/2014 [i.1].
In particular:
CAS-4.1-02: The conformity assessment scheme shall, with the aim of confirming that the assessed QTSP/QTS fulfils
the applicable requirements from Regulation (EU) No 910/2014 [i.1], include:
a) requirements on the CAB, including on the auditing rules under which the CAB will carry out its conformity
assessment and on the effective set of criteria, meeting at least requirements from ETSI EN 319 403 [1]; and
NOTE: This de facto implies the CAB being compliant with ETSI EN 319 403 [1], hence with
ISO/IEC 17065 [i.30], to be a certification body and the conformity assessment scheme to be a
certification scheme [i.30].
b) control objectives and controls against which the CAB will assess a QTSP/QTS against the applicable
requirements of Regulation (EU) No 910/2014 [i.1].
ETSI
---------------------- Page: 9 ----------------------
10 ETSI TS 119 403-3 V1.1.1 (2019-03)
CAS-4.1-03: The resulting conformity assessment report shall meet the requirements of clause 4.2 of the present
document.
4.2 Conformity assessment report
CAR-4.2-01: The Conformity Assessment Report (CAR) shall bear a clear certification decision conformant to
clause 7.6 of ETSI EN 319 403 [1], confirming - if such is the case - that the assessed QTSP/QTS meet all the
applicable requirements of Regulation (EU) No 910/2014 [i.1].
CAR-4.2-02: The CAR shall provide sufficient details to demonstrate that the assessed QTSP/QTS fulfil all the
applicable requirements laid down in Regulation (EU) No 910/2014 [i.1].
NOTE 1: Those details and information demonstrating QTSP/QTS compliance with Regulation (EU)
No 910/2014 [i.1] requirements can be included by reference to other reports, e.g. such as audit reports
against technical standards, which contain detailed and herewith sufficient information for the SB to
judge the QTSP/QTS conformity to the Regulation. On top of that the SB can be pointed to the security
documentation of the QTSP, like the security concept, its declaration of practices and/or of policies, etc.,
as it can be referenced in the CAR.
In particular:
CAR-4.2-03: The CAR shall identify the name of the CAB, and where applicable its registration number, as stated in
the official records, its official postal address and its electronic address.
CAR-4.2-04: The CAR shall identify:
a) the name of the NAB having accredited the CAB;
b) the link, on the official website of the NAB, to the accreditation certificate issued by the NAB to the CAB; and
c) when not mentioned in the accreditation certificate:
i) the scheme under which the CAB has been accredited in the context of Regulation (EU)
No 765/2008 [i.3]; and
EXAMPLE 1: Such a scheme can be ISO/IEC 17065 [i.30] being completed by ETSI EN 319 403 [1].
ii) the conformity assessment (certification) scheme for which the CAB has been accredited to conduct
conformity assessment of QTSP/QTSs against the requirements laid down in Regulation (EU)
No 910/2014 [i.1].
CAR-4.2-05: The complete CAR shall be considered as part of the certification documentation specified in clause 7.7
of ETSI EN 319 403 [1].
CAR-4.2-06: The CAR shall include the accredited conformity assessment (certification) scheme document (or set of
documents) or a link to the location from where that document (or set of documents) is available.
CAR-4.2-07: The CAR shall bear EU qualified electronic signature(s) identifying the name and title of the CAB
responsible person(s) having authorized the certification decision.
CAR-4.2-08: The CAR shall be dedicated to one and only one QTSP, in particular:
a) the CAR shall identify the name of the assessed QTSP, and where applicable its registration number, as stated
in the official records, its official postal address and its electronic address; and
b) when applicable, the CAR shall identify this same information of all subsidiaries, affiliated legal entities and
(sub)contractors that are operating trust service components in scope of the provision of (Q)TS by the QTSP,
and hence in scope of the certification decision.
NOTE 2: QTSPs can make use of third parties, whether (Q)TSPs or not, to operate part or all of the service
components of the QTS they provide. In this situation, the QTSP remains the final entity responsible and
liable for the QTS it provides and needs to document and ensure correct implementation of those service
components against its declared practices and policies as well as against Regulation (EU)
No 910/2014 [i.1].
ETSI
---------------------- Page: 10 ----------------------
11 ETSI TS 119 403-3 V1.1.1 (2019-03)
CAR-4.2-09: The CAR shall identify, in accordance with clause 5.5.3 of ETSI TS 119 612 (V2.1.1) [2], the service
digital identity(ies) per type of QTS for which the CAR confirms the conformity with the requirements of Regulation
(EU) No 910/2014 [i.1] providing at least:
a) the Subject Key Identifier as defined in IETF RFC 5280 [3];
b) the Base64 PEM representation of the associated X.509v3 digital certificate;
c) when applicable, an indication whether specific sets or subsets of end-entity certificates issued by or under the
service digital identity are excluded from the certification decision and on the basis of which criteria they can
be identified;
EXAMPLE 2: Such criteria can be a list of certificate policy identifiers to match with the content of the
CertificatePolicy certificate extension as defined in IETF RFC 5280 [3] or other criteria as defined
in clause 5.5.9.2.2 of ETSI TS 119 612 (V2.1.1) [2].
d) an indication whether the service digital identity relates to an end-entity or a certification authority, clarifying
whether an issuing, intermediate or root; and
e) an indication on how the service digital identity is used in the context of the corresponding QTS.
EXAMPLE 3: The private key corresponding to the service digital identity can be used to digitally sign
(qualified) certificates, qualified electronic time stamps, evidences in the context of qualified
electronic registered delivery, in the context of qualified validation of qualified electronic
signatures or seals, or in the context of qualified preservation of qualified electronic signatures or
seals.
CAR-4.2-10: In line with CAR-4.2-09, per type of QTS and for all service digital identities identified in CAR-4.2-09,
the CAR shall provide a detailed description of the PKI functional hierarchy with the purpose to allow identification of
the service entry(ies) to be listed in the applicable national trusted list in accordance with CID (EU) 2015/1505 [i.2],
including at least:
a) the illustration of the PKI hierarchy identifying the root certification authority(ies), the intermediate
certification authority(ies), the issuing certification authority(ies) and the certification paths between them;
b) the identification of each certification authority illustrated in point a) through the Subject Key Identifier as
defined in IETF RFC 5280 [3];
c) for each of the issuing CAs identified in point b), the list of the different (policy) sets of certificates such a CA
is issuing, with for each set:
i) a criteria that unambiguously identifies the certificates of the set, being either a list of certificate policy
identifiers to match with the content of the CertificatePolicy certificate extension as defined in IETF
RFC 5280 [3] or other criteria as defined in clause 5.5.9.2.2 of ETSI TS 119 612 (V2.1.1) [2];
ii) an indication whether the certificates of the set are either qualified or non-qualified;
iii) an indication whether the certificates of the set are either for electronic signatures, or for electronic sea
