【Abstract】 This paper combines the fundamental ideas of forward security and blind signature to design a forward-secure strong blind signature scheme based on ElGamal. The security of the proposed scheme is based on the assumption of difficulty in solving the discrete logarithm problem in the finite field. With the detailed analysis of security, the proposed scheme not only has the features of forward-secure, strong blindness and resisting forging attack, but also has certain theoretical and practical values.更多还原
