摘　　要：该文讨论了在一个发送者、多个接收者、多重认证码中、内部欺骗者的联合实施模仿攻击和替代攻击成功概率的下界。说明了对多接收多重认证门限体制,要使它达到某一安全水平,发送者和各接收者必须掌握的最小密钥量,并给出一种具体构造方法。This paper discusses the bounds on the probability of success in impersonation and substitution attack by malicious groups of receivers for multiple authentication codes with multi-receiver, and gives out the least-size of the secret key space that the sender and the receivers must have in hand to ensure the multiple authertication codes with multi-receiver being under security level and presents also its construting method.
