Hwang and Chen recently proposed new multi-proxy multi-signature schemes that allow a group of authorized proxy signers to sign messages on behalf of a group of original signers. ...
The internal state of the Klimov–Shamir number generator TF-1 consists of four words of size w bits each, whereas its intended strength is 22w. We exploit an asymmetry in its out...
Recently, Harn proposed an efficient scheme that can batch verification multiple RSA digital signatures. His scheme can reduce signature verification time. However, there is a weak...
