A secure channel for attribute-based credentials
Gergely Alpár, Jaap-Henk Hoepman · 2013
Attribute-based credentials (ABCs) are building blocks for user-centric identity management. They enable the disclosure of a minimum amount of information about their owner to a verifier, typically a service provider, to authorise the credential owner for some service, application, or resource. By directly applying attribute-disclosure protocols, the data is revealed not only to the verifier, but anyone who has access to the communication channel. Moreover, as verifiers are not intrinsically authenticated, one can accidentally reveal attributes to the wrong party. Therefore, a secure channel has to be established between the prover and the verifier.
