Abstract: This paper shows the security flaw which extends from the multisignature scheme based on Meta-El Gamal,i.e.,the attackers can deny having taken part in the process of signing some message with others.A modification is made for these schemes’ key generations,which can efficiently avoid this attack.

Key words: Meta-El Gamal, multisignature, schemes' key generation
