Addo Sign complies with eIDAS

Digital transactions and remote collaboration have become an integral part of everyday life for both private and public organizations. To ensure these interactions are reliable and compliant with current legislation, the eIDAS Regulation – Electronic Identification, Authentication and Trust Services – plays a crucial role. It establishes the legal framework for electronic signatures in the EU and ensures that digital signatures have the same legal validity as physical ones.

This article explains why eIDAS is a recognized and secure standard for digital signing – and how Addo Sign supports the requirements in practice.

What is eIDAS?

eIDAS stands for Electronic Identification, Authentication and Trust Services, and is an EU regulation that came into effect in July 2016. Its aim is to ensure a consistent, secure, cross-border digital identity and signature infrastructure throughout the EU, so citizens, businesses, and authorities can act safely and efficiently online.

Legal Recognition and Standardisation

The eIDAS regulation establishes common rules for the validity of electronic signatures and identification across member states. This means a digital signature created in one member state must be recognised as valid in all others – just like a handwritten signature. Each member state must maintain a public list of Qualified Trust Service Providers (QTSPs) that meet the regulation’s security requirements.

 

Three Levels of Security

eIDAS divides electronic signatures into three levels of security and legal effect:

  • Electronic Signature (ES): A basic e-signature, e.g. typing your name in an email or ticking a box in a form.

  • Advanced Electronic Signature (AES): A signature uniquely linked to the signer, capable of identifying them, and allows detection of data manipulation.

  • Qualified Electronic Signature (QES): The highest security level, requiring a qualified signature creation device and a qualified certificate issued by a QTSP. A QES has the same legal status as a handwritten signature across the EU.

This structure allows you to select the appropriate signature level for your security and legal requirements.

Addo Sign and eIDAS

Addo Sign supports both AES and QES in accordance with the eIDAS regulation when used with a qualified trust provider. We partner with InfoCert—an EU‑approved QTSP—to satisfy all technical and legal requirements for AES or QES. This makes signatures made via Addo Sign just as binding as pen‑and‑paper ones.

Advanced Cryptography and Security

Digital signatures under eIDAS use advanced cryptography—such as asymmetric encryption, hash functions, and secure key management—to ensure data integrity and authenticity. These technologies make forgery or tampering extremely difficult.

Cross-Border Recognition

One of eIDAS’s key advantages is the mutual recognition of electronic signatures across the EU. A signature issued in one country is valid in any other member state, promoting trust and efficiency in cross-border transactions.

eIDAS 2.0 and Digital Identity

In 2024, eIDAS was updated to include eIDAS 2.0, introducing the European Digital Identity Wallet. This digital wallet enables citizens and businesses to identify themselves and securely share documentation across borders, and Addo Sign is actively integrating to meet future standards.

A Secure, Future-Proof Solution

Addo Sign is built on eIDAS principles and meets all technical and legal requirements for digital signing. Combining modern technology, qualified trust services, and EU standards, Addo Sign delivers a secure, reliable, and legally binding solution—today and tomorrow.
