摘　　要：给出基于Schnorr数字签名体制的顺序群签名方案.描述了这个顺序群签名体制的密钥生成、群签名生成和群签名验证过程,指出它们对群签名的有效性.讨论这个群签名体制的安全性,利用计算复杂度理论证明了它对抗被动攻击和Schnorr数字签名体制是同样安全的.A digital sequential multisignature scheme was given on the basis of Schnorr digital signature scheme. The password key generation, multisignature generation and multisignature verification were described with respect to this scheme. It was pointed out that it was especially efficient for sequential multisignature. The security of the sequential digital multisignature scheme was discussed and it was also proved by using the computational complexity theory that it was as secure as the Schnorr scheme against the passive attack.
