eIDAS stands for 'electronic Identification, Authentication and trust Services.' It is a European Union regulation (Regulation (EU) No 910/2014) that establishes standards for electronic identification and trust services for electronic transactions within the EU’s internal market. The regulation aims to enhance trust and security in digital transactions by providing a predictable regulatory environment. eIDAS covers aspects such as electronic signatures, electronic seals, time stamps, electronic delivery services, and website authentication. It ensures that electronic identification and trust services are recognized across EU member states, facilitating secure cross-border digital business and public services. The regulation is crucial for digital transformation and secure e-government in Europe.
