There are many cryptographic schemes with anonymity, such as group signatures. As one important property, anonymity revocation has been introduced. In such schemes, the fact of
whether a signer’s rights have been revoked or not
is important additional information. For example, if a third party knows that there are many revoked members in a company, then the company’s reputation may be damaged in many ways. People may think that
there might be many problematic employees (who have bad behavior-s) in this company
there might be many people who have quit, i.e., the labor environment may not be good
, and so on. To avoid such harmful rumors, in this paper, we propose an Anonymous Designated Verifier Signature (ADVS) scheme with revocation. In ADVS, a designated verifier can only verify a signature anonymously, and a third party cannot identify whether the rights of the signer have been revoked or not. We show two security-enhanced schemes as applications of our scheme: a biometric-based remote authentication scheme, and an identity management scheme.
