Abstract:


A proxy signature scheme is a variation of the ordinary digital signature scheme which enables a proxy signer to generate signatures on behalf of an original signer. In this paper, we present a secure proxy signature scheme. The proposed proxy signature for warrant partial delegation combines an advantage of two well known warrant partial delegation schemes. The proposed proxy signature scheme is based on the difficulty of solving the discrete logarithm problem. We prove that the proposed proxy signature scheme meets the security requirements for a proxy signature scheme.
