(A.) Policy and legislation

(A.1) Policy objectives

This relates to Regulation (EU) No 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC.

(A.2) EC perspective and progress report

In the context of the e-signatures Directive, in January 2010, the Commission mandated the ESOs to rationalise the standards for e-signatures and related trust services to form a coherent and up-to-date framework (mandate M/460).

The eIDAS Regulation adopted on 23 July 2014 addresses in one comprehensive piece of legislation, electronic identification, electronic signatures, electronic seals, electronic time stamping, electronic registered delivery services, electronic documents and certificate services for website authentication as core instruments for electronic transactions. To support the implementation of this highly technical regulation, further standardisation work will be needed. In the case of  trust services, the planned secondary legislation refers extensively to the availability of standards as possible means to meet the regulatory requirements. Existing standards should be checked to take account of the protection of individuals with regard to personal data processing and the free movement of such data. Specific privacy by design standards should be identified and where needed developed. The accessibility needs of persons with disabilities should also be taken into account.

(B.) Requested actions

Action 1   Build on the work done under Mandate M/460, in the following way: Support harmonisation of identity proofing, particularly in relation certificate issuance and remote signing.  Define extended validation procedures that can be followed to determine if a signed document might be wrongly interpreted, even if the signed bytes have not changed.

Action 2  Take ongoing EU policy activities into account in standardisation, e.g. in ISO/IEC JTC 1/SC 27/WG 5 (identity management and privacy technologies) and other working groups of ISO/IEC JTC 1/SC 27. Furthermore, in order to promote the strengths of the European approach to electronic identification and trust services at global level and to foster mutual recognition of electronic identification and trust services with non-EU countries, European and international standards should be aligned wherever possible. The promotion and maintenance of related European approaches, which especially take into account data protection considerations, in international standards should be supported.

Action 3 Support and improve the development of interoperable standards by facilitating the organisation of plugtests (interoperability events) and developing and enhancing conformity testing tools. Such interoperability events may address CAdES, XAdES, PAdES, ASiC, use of trusted lists, signature validation, remote signature creation and validation, e-delivery services, preservation services, etc.

Action 4 Foster the development of standards supporting the implementation of the measures derived from the revision of the eIDAS regulation, aimed to improve its effectiveness, extend its benefits to the private sector and promote trusted digital identities for all Europeans.

Under the Security, Infrastructure and Trust Working Group led by ITU under the Financial Inclusion Global Initiative (a joint programme of the ITU, World Bank and Bank for International Settlements and supported by the Gates Foundation), studies on strong authentication technologies applications for digital financial services are being undertaken. The studies describe several widely-adopted technical and policy standards that support strong authentication mechanisms. The examples of strong authentication and advanced authentication systems are categorized as either enrolment or authentication for the use of DFS. These two use case categories primarily impact users of DFS. The use of identity verification and authentication system based on DLT are also being studied. See Report:


The United Nations Economic Commission for Europe in its Recommendation 14 outlines base elements to take into account in the use of electronic authentication methods. It recommends that the authentication methods should be chosen in light of the nature of the electronic transaction and the relationship between the parties involved in the exchange. Not all electronic exchanges require the highest level of reliability.

Further work is being developed on this topic within UN/CEFACT. See:


The OASIS Security Services (SAML) TC maintains and extends the widely used Security Assertion Markup Language (SAML, also ITU-T Recommendation X.1141) standard. A profile of SAML is used for cross-border identification and authentication of citizens in the eIDAS nodes provided by the eID Building Block of the Connecting Europe Facility (CEF). SAML is also used at national level in Member States.

The OASIS Trust Elevation TC defines a set of standardized protocols that service providers may use to elevate the trust in an electronic identity credential presented to them for authentication.

The OASIS DSS-X TC defines standard Digital Signature Service Core Protocols, Elements, and Bindings. The latest version provides both JSON- and XML-based request/response protocols for signing and verifying, including updated timestamp formats, transport and security bindings and metadata discovery methods. This TC works in close liaison with the ETSI Electronic Signatures and Infrastructures (ESI) TC.

The OASIS ebXML Message TC maintains the OASIS ebMS3 (also ISO 15000-1) standard and the AS4 standard (also ISO 15000-2). AS4 is profiled as the message exchange protocol of the eDelivery Building Block of the Connecting Europe Facility. Several dozens policy domains use eDelivery for cross-border secure and reliable exchange of documents and data. AS4 is also used in the EESSI system for digitalisation in social security coordination.

The OASIS Business Document Exchange TC provides complementary eDelivery specifications for service location and capability lookup.


Set of standards and related certification profiles addressing identity transactions over the internet. Active working groups in this area include: the OpenID Connect WG, AccountChooser WG, Native Applications WG, Mobile operator Discovery, Registration and Authentication WG (MODRNA), Health Related Data Sharing WG (HEART), and Risk and Incident Sharing and Coordination WG (RISC)


The Web Authorization Protocol (OAUTH) WG developed a protocol suite that allows a user to grant a third-party Website or application access to the user’s protected resources, without necessarily revealing their long-term credentials, or even their identity. It also developed security schemes for presenting authorisation tokens to access a protected resource.

The ongoing standardisation effort within the OAUTH Working Group is focusing on enhancing interoperability of OAUTH deployments.

The Public Notary Transparency (TRANS) WG develops a standards-track specification of the Certificate Transparency protocol (RFC6962) that allows detection of the miss-issuance of certificates issued by CAs or via ad-hoc mapping by maintaining cryptographically verifiable audit logs.

The Automated Certificate Management Environment (ACME) WG specifies conventions for automated X.509 certificate management, including validation of control over an identifier, certificate issuance, certificate renewal, and certificate revocation. The initial focus of the ACME WG is on domain name certificates (as used by web servers), but other uses of certificates can be considered as work progresses.


The W3C Credentials Community Group discusses credential storage and exchange systems for the web. Some of their ideas are being discussed in the Web Payments Interest Group via the Verifiable Claims Task Force (as of January 2016).

The Verifiable Claims Working Group specifies ways to make expressing, exchanging, and verifying claims easier and more secure on the Web. It released the Verifiable Credentials Data Model 1.0 Proposed Recommendation on 05 September 2019. This specification provides a mechanism to express these sorts of credentials on the Web in a way that is cryptographically secure, privacy respecting, and machine-verifiable. The W3C Note of 24 September 2019 is a collection of use cases for the Verifiable Credentials Data Model 1.0 and helps to better understand that Specification.
