A Secure Proxy Signature Scheme with Delegation by Warrant

A proxy signature scheme is a variation of the ordinary digital signature schemes which enables a proxy signer to generate signatures on behalf of an original signer. In this paper, we present a secure proxy signature scheme. Our proxy signature scheme is based on the difficulty of solving the discrete logarithm problem. We prove that our proxy signature scheme meets all the security requirements for a proxy signature scheme.
