A forgery attack is presented on the self-certified signature scheme.The results show that CA can forge a valid self-certified signature of his client on an arbitrary message by tampering with some parameters of the signature.An improved scheme is proposed to resist this kind of forgery attack.Analyses show that the improved scheme has the same security features with Schnorr signature.
