Abstract. An oblivious signature with n keys (or messages) is a signature that the recipient can choose one of n keys (or messages) to get signed while the signer cannot find out o...
In a blind signature scheme, the user can get a signature sig(m) on message m generated from the signer's blind signature sig(m ) on blinded message m , but the signer can...
Abstract. A feasible solution to prevent potential misuse of signatures is to put some restrictions on their verification. Therefore S.J.Kim, S.J.Park and D.H.Won introduced the n...
We first analyze the security of a short signature scheme without random oracles called ZCSM scheme and point out that it cannot support unforgeable under the chosen message and ...

The standard digital signature scheme can be easily subject to key exposure problem In order to overcome this problem; a feasible and effective approach is employed by key-evolving...
