Abstract

Designated verifier signatures are privacy-oriented signatures that provide message authenticity only to a specified verifier but nobody else. We consider strong multi-designated verifiers such that knowledge of either one of designated verifiers’ private keys is required to verify the signature. We propose the first identity-based construction.
