This paper gave security analysis of the multisignature schemes——Luo et al.'s forward-secure multisignature scheme based on ElGamal type.The scheme didn't meet property of forward security while some signer's key was compromised.LUO's scheme could't resist forge attack.And finally,proposed the new improved scheme,analysed its security.The scheme can effectively resist forge attack and coordinate attacks.It's a safe,efficient,practical and forward secure multisignature scheme.
