Session Abstract: The European Union’s regulation on digital identity, eIDAS, is currently being overhauled to adopt decentralized identity principles. The goal is to provide all citizens and residents across the EU with highly secure and privacy-preserving digital wallets that can be used to manage various digital credentials, from eIDs to diplomas to payment instruments. Decentralized identity principles aim at giving freedom of choice and control to the end user. Ensuring security and interoperability, however, will be challenging — especially with the enormous scale of users and use cases the EU is targeting. The choices made in eIDAS will have a huge impact on digital identity in the EU and beyond. The so-called “Architecture and Reference Framework” defines the technical underpinnings of eIDAS v2. Many experts from member states and the EU Commission have been working on this framework over the last year, trying to select the best combination of technologies and standards out of the vast number available in the market today. This talk will introduce that framework and explain what architectural patterns and technical standards are adopted. We'll also look at how the challenges mentioned are addressed to realize the vision of the eIDAS v2 regulation.
