摘　　要：在一个群通信体系中,最基本并且最具有实际意义的认证系统是指关于动态发送者的多接收认证码(简称DMRA-code)。但目前,许多学者对其研究仅仅局限于对一个信源的认证。然而在网络通信中,常常会有多信源传播的场景。基于这个问题,利用多项式构造一个具有动态发送功能的多信源认证码,并且验证了该模型的合理性以及计算出了可能的攻击概率,从而保证了所构造的方案的安全性。In a group communication system, the basic authentication systems refer to the multi-receiver authentication codes with dynamic senders （DMRA-code）. At present, many scholars have a lot of researches, in which the authentication of source state is restricted as only one. However, in the network communication, there are al- ways scenarios in which multiple source states are required to be authenticated. Based on this problem, a multiple message authentication code with dynamic senders is constructed with symmetric polynomials. In ad- dition, the probabilities of possible attacks are computed to ensure the scheme security.
