Abstract. In this paper, we provide the first committed signature provably secure in the standard complexity model based on the strong RSA assumption. The idea behind the construc...
The concept of public-key cryptography was invented in 1976 by Diffie and Hellman [DH]. The following year, Rivest, Shamir and Adleman provided an implementation of this idea [RSA]...
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 ...
