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 couldnt have identified the actual signer .In this paper our proposed schemes realize unconditional anonymity .
Key words： analogous ring signature; identity; unconditional security
