Abstract: In order to hide the identity of a signer, an anonymous signaure scheme is presented in this paper. In this scheme, a signer located in a specified group produces a signautre on behalf of the group. The recipient can verify whether the signature is valid and comes from the specified group, while tracing the signature to its source is impossible. The proposed anonymous signature is similarly to ring signature in some respects, for example, there is no manager, and no revocation mechanism against signer's anonymity. The most different between these two kinds of signatures is that the group in ring signature is adaptively constructed by the signer, while the group in our scheme is fixed.
