On 12 October, EBSI had the honour of presenting at the ENISA & eID Trust Services Forum about the evolving subject of Revocation of Verifiable Credentials (VCs). Lead architect Alen Horvat talked with the audience about EBSI’s Credential Status Framework and our newly published study on revocation methods for W3C VCs.

Recognising the need for Revocation

One of EBSI’s main goals is to establish an infrastructure that supports the sharing of important information as Verifiable Credentials. These digital credentials represent a more secure, privacy-preserving and efficient way of verifying and sharing our data when needed. But this new system also comes with a unique challenge: what do we do when a credential needs to be revoked?

At times, a credential may ‘go bad’, and thus need to be revoked. However, given that with Verifiable Credentials this information is shared from digital wallets, without contacting the issuer, determining a method for revocation that also does not require contacting the issuer is challenging.

EBSI’s new in-depth white paper presents our study on the complexities of credential revocation and explores solutions that limit the need for communication between issuers and verifiers.

Spreading the word about Revocation

EBSI’s presentation at the ENISA & eID Trust Services Forum outlined this exact topic, with a deck titled ‘What to do when good credentials go bad?’

The deck presents EBSI’s critical criteria when it comes to revocation. Specifically, we aim to uphold the following principles:

  • We adhere to GDPR.
  • We prevent holder traceability.
  • We respect the privacy of holders.
  • We do not store or process personal data on the EBSI blockchain.
  • We prevent issuers or third parties from linking revocation checks with the holders.
