In this paper we present a simple protocol that allows a user to prove to a verifier possession of a credential. Credentials can be revoked simply by publishing ...
Abstract. Secret Handshake is becoming an ever more popular research subject in the field of privacy- preserving authentication protocols. Revocation of ...
A Secret Handshake scheme supports reusable Credentials if some form of Anonymity and Unlinkability are guaranteed and users receive a single Credential.
The schemes proposed in the literature are either limited versions of secret handshake supporting revocation, or they support more complete versions of secret ...
Abstract. Revocation of credentials in Secret Handshakes is a difficult challenge, as it mixes the conflicting requirements of tracing revoked.

Who has a secret handshake?
These scenarios demand the system to have a timely and effective revocation mechanism such that those members' credential should be nullified and the ...
In this paper, a backward unlinkable secret handshake scheme with revocation support (BU-RSH) is constructed.
In this paper, we study this problem and propose a generic approach to provide revocation support in secret handshake protocols, without sacrificing the notion ...
We provide a proof of security for GSPR in the random oracle model using the decisional linear assumption and the bilinear strong Diffie-Hellman assumption.
Secret Handshakes are well-established cryptographic primitives that help two mistrusting users to establish initial trust by proving and verifying ...
