Abstract:

This paper presents two ID-based analogous ring signature schemes in which any user can sign on behalf of the set to which he belongs , but a verifier can't tell which member actually produced the digital signature .For an attacker , even if he had known all the secret signing keys , he couldnt have identified the actual signer .In this paper our proposed schemes realize unconditional anonymity .

Key words: analogous ring signature, identity, unconditional security
