Abstract: A weakness in a multisignature scheme designed by E.Chida is pointed out here, this scheme is not strong enough to resist the internal attack. And an improved multisignature scheme based on the one-way algebraic homomorphism is presented and its security level is as same as DSAsignature scheme at least.

Key words: cryptography, digital multisignature, one-way algebraic homomorphism
