摘　　要：带仲裁的认证码(A2-码)能解决通信系统中发方与收方互不信任的问题.利用辛几何构造了一类新的A2-码.计算了码的参数,当编译码规划都按等概率分布选取时,计算出各种攻击成功的概率.Authentication code with arbitration （-code） can solve the problem of transmitter/reciver disputes in comunication system. A new code based on sympletic geometry is given. The parameters of the code are computed, and as all the rules of the transmitter and the receiver are chosen according to an equal probability distribution, the probabilityies of success for different type of deceptions are also computed.

关 键 词：认证码 仲裁 辛几何
