Abstract :
A small size group signature scheme based on RSA cryptosystem is described in this paper. Due to the special algebraic structure of RSA, one public key and two corresponding private keys are available. The two private keys are used as signature keys for group members. The signature operation includes an ordinary RSA signature and a zero knowledge proof about signature key. Compared with most group schemes, it has low computational cost as to signature and verification.
