Recently, based on RSA and discrete logarithm with composite modulus, Huang and Chang proposed two multisignature schemes with distinguished signing authority and claimed that the...
In certain reliable group-oriented and multicast applications, a source needs to securely verify whether all (and if not all, which) intended receivers have received a message. How...

A proxy signature scheme enables a proxy signer to sign messages on behalf of the original signer. In this paper, we demonstrate that a number of discrete logarithm based proxy si...
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...
