epicenter.works Proposes Amendments to the EUDI Wallet

A new paper from digital rights group epicenter.works takes an engineering-centred look at the European Commission’s draft eIDAS implementing acts for the European Digital Identity (EUDI) Wallet ¹.

Rather than debating the policy goals, it focuses on whether the technical rules will actually let wallets enforce privacy and security in real time – when a user is about to share data. The proposed amendments cover three areas: relying-party registration, electronic attestations of attributes (EAAs), and the technical specifications intended to make the ecosystem interoperable.

One of the paper’s headline concerns is relying-party registration. It argues that registration certificates should be mandatory because without them a wallet has no clean cryptographic handle for checking whether a request is legitimate and within scope. In other words: if a service asks for an attribute, the wallet should be able to automatically verify what that service is authorised to request, and flag ‘over-asking’ before anything is disclosed.
