• We propose a new blind signature scheme based on RSA digital signature. Our blind signature scheme proposed in this work has a merit as compared with Chaum's scheme that it doesn't necessary to use a random number and signer's public key on the protocol. But our blind signature scheme has a defect that it accompanies message expansion by a factor of two. We present security analysis of the proposed scheme that its security depends on the discrete logarithm problems in an appropriate cyclic groups. Moreover proposed blind signature scheme is well applied to untraceable electronic cash.
