Revocable Anonymity of Undeniable Signature Scheme

We present a new revocable anonymous protocol for the undeniable signatures. Our scheme allows some designated entity for example the government to revoke the anonymity of some signer who has done illegal actions in the group. Our scheme improves the signing algorithm of the traditional undeniable signatures such that the signing algorithm is more efficiency referring to the time and space cost.
