Abstract. We revisit the notion of the anonymous signature, first formalized by Yang, Wong, Deng and Wang [12], and then further developed by Fischlin [6] and Zhang and Imai [13]. ...
A (t, n) threshold proxy signature scheme enables an original signer to delegate the signature authority to a proxy group of n member such that t or more than t proxy signers can ...
To enhance the efficiency of threshold group signature schemes, Yu and Chen, recently, proposed an efficient threshold group signature scheme. By using elliptic curves, the propos...
A directed signature scheme allows a designated verifier to directly verify a signature issued to him, and a third party to check the signature validity with the help of the signe...
