摘　　要：本方案是在王家岭方案基础上,引入零知识证明方法防止非法成员对合法成员的欺骗,得到一个更安全的防欺骗多秘密共享方案。在初始阶段,加强某些参数限制条件,使其满足算法;在验证阶段,引入零知识证明方法验证参与者的合法性,以防止非法成员对合法成员的欺骗;在秘密恢复阶段,使用联立线性方程组和高斯消元法恢复秘密;本方案使用Java语言来实现,实验验证了该方案的可行性。Based on Jialing-Wang＇s scheme,this scheme is the introduction of interactive zero-knowledge proof method to prevent illegal members to deceive members of the legal members;it gets a more secure multi-secret sharing scheme against cheating.In the initial phase,to strengthen restrictions of some parameters make them meet the algorithm;in the validation phase,in order to prevent illegal to deceive members of the legal members,it is the introduction of interactive zero-knowledge proof method for verification of the legality of the participants;in the secret recovery phase,the use of joint simultaneous linear equations and Gaussian elimination method recover from the sharing secrets;the implementation of improvement scheme is using JAVA language,the experiment verify the feasibility of the scheme.
