The Crucial Role of Web Protocols and Standards in Digital Wallet Ecosystems (god2024)

Chaos Computer Club - recent events feed

In the coming years, all EU member states will be required to provide their citizens with a digital identity wallet, as mandated by the European Union. The EU Digital Identity Wallet (EUDI Wallet) represents the largest implementation of its kind to date and brings with it significant challenges, particularly in terms of security, privacy, and interoperability. To address these challenges, the EU has chosen to leverage open standards widely adopted in the web ecosystem — such as OpenID for Verifiable Presentations (OpenID4VP) based the widely-used web standard OAuth 2.0, and Selective Disclosure JWT (SD-JWT) built on the JSON Web Token (JWT) framework. However, wallet ecosystems operate quite differently from the traditional web, requiring adaptations to these protocols to meet the unique demands of secure, decentralized identity management. This talk will provide a comprehensive overview of the EUDI Wallet's architecture and the key challenges posed by adapting native web protocols for wallet ecosystems. It will also explore the crucial role browser vendors will play in ensuring the security and smooth functioning of this new digital identity landscape.
