The EU trust mark for qualified trust services.
The EU digital single market and the facilitation of public services across borders.

eIDAS (electronic IDentification, Authentication and trust Services) is an EU regulation on / a set of standards for electronic identification and trust services for electronic transactions in the European Single Market. It was established in EU Regulation 910/2014 of 23 July 2014 on electronic identification and repeals directive 1999/93/EC from 13 December 1999.[1][2]

It entered into force on 17 September 2014 and applies from 1 July 2016 except for certain articles, which are listed in its Article 52.[3] All organizations delivering public digital services in an EU member state must recognize electronic identification from all EU member states from September 29, 2018.[4][5]


eIDAS oversees electronic identification and trust services for electronic transactions in the European Union's internal market. It regulates electronic signatures, electronic transactions, involved bodies, and their embedding processes to provide a safe way for users to conduct business online like electronic funds transfer or transactions with public services. Both the signatory and the recipient can have more convenience and security. Instead of relying on traditional methods, such as mail or facsimile, or appearing in person to submit paper-based documents, they may now perform transactions across borders, like "1-Click" technology.[2][6]

eIDAS has created standards for which electronic signatures, qualified digital certificates, electronic seals, timestamps, and other proof for authentication mechanisms enable electronic transactions, with the same legal standing as transactions that are performed on paper.[7]

The regulation came into effect in July 2014, as a means to facilitate secure and seamless electronic transactions within the European Union. Member states are required to recognise electronic signatures that meet the standards of eIDAS.[2][8]


eIDAS is a result of the European Commission's focus on Europe's Digital Agenda. With the Commission's oversight, eIDAS was implemented to spur digital growth within the EU.[9]

The intent of eIDAS is to drive innovation. By adhering to the guidelines set for technology under eIDAS, organisations are pushed towards using higher levels of information security and innovation. Additionally, eIDAS focuses on the following:[8][10]

  • Interoperability: Member states are required to create a common framework that will recognize eIDs from other member states and ensure its authenticity and security. That makes it easy for users to conduct business across borders.
  • Transparency: eIDAS provides a clear and accessible list of trusted services that may be used within the centralised signing framework. That allows security stakeholders the ability to engage in dialogue about the best technologies and tools for securing digital signatures.

Regulated aspects in electronic transactions[edit]

The Regulation provides the regulatory environment for the following important aspects related to electronic transactions:[2]

  • Advanced electronic signature: An electronic signature is considered advanced if it meets certain requirements:
    • It provides unique identifying information that links it to its signatory.
    • The signatory has sole control of the data used to create the electronic signature.
    • It must be capable of identifying if the data accompanying the message has been tampered with after being signed. If the signed data has changed, the signature is marked invalid.
    • There is a certificate for electronic signature, electronic proof that confirms the identity of the signatory and links the electronic signature validation data to that person.
    • Advanced electronic signatures can be technically implemented, following the XAdES, PAdES, CAdES or ASiC Baseline Profile (Associated Signature Containers) standard for digital signatures, specified by the ETSI.[11]
  • Qualified electronic signature, an advanced electronic signature that is created by a qualified electronic signature creation device based on a qualified certificate for electronic signatures.
  • Qualified digital certificate for electronic signature, a certificate that attests to a qualified electronic signature's authenticity that has been issued by a qualified trust service provider.
  • Trust service, an electronic service that creates, validates, and verifies electronic signatures, time stamps, seals, and certificates. Also, a trust service may provide website authentication and preservation of created electronic signatures, certificates, and seals. It is handled by a trust service provider.

Evolution and legal implications[edit]

The eIDAS Regulation evolved from Directive 1999/93/EC, which set a goal that EU member states were expected to achieve in regards to electronic signing. The directive made EU member states responsible for creating laws that would allow them to meet the goal of creating an electronic signing system within the EU. As it is a regulation, it became directly binding as law throughout the EU from July 1, 2016.[12]

eIDAS provides a tiered approach of legal value. It requires for no electronic signature to be denied legal effect or admissibility in court solely because it is not an advanced or qualified electronic signature.[13] Qualified electronic signatures must be given the same legal effect as handwritten signatures.[14]

For electronic seals (legal entities' version of signatures), probative value is explicitly addressed, as seals should enjoy the presumption of integrity and the correctness of the origin of the attached data.[15]
