Providing End-to-End Guaranteed QoS in A-Serv Architecture

A proxy signature scheme enables a proxy signer to sign messages on behalf of the original signer. In this paper we propose an efficient proxy signature scheme based on RSA signature scheme, which divides the document M into m blocks and adds some redundant bits to each message block. We also give a kind of algorithm of the zero-knowledge proof of proposed digital signature. This algorithm has characteristics which has little computation, high reliability, and easy to be realized. The proposed signature scheme satisfies the secure requirements and is efficient.
