Construction of Authentication Codes with Atrbitration from Singular Pseudo-sympolectic Geometry

利用有限域上奇异伪辛几何构作了一个具有仲裁的认证码,计算了这个码的参数,当发方编码规则和收方解码规则按等概率分布选取时,计算出各种攻击成功的概率。

A construction of authentication codes with arbitration from singular pseudo-symplectic geometry over finite fields is presented, and the parameters of the code are comptued. Assuming that the encoding rules of the transmitter and the receiver are chosen according to a uniform probability distribution, the probabilities of success for different type of deceptions are also computed.
