利用有限域上酉几何构作一类新的带仲裁的认证码,并且计算了所构作认证码的参数以及各种攻击成功的概率.
A construction of authentication codes with arbitration from unitary geometry over finite fields is given and the parameters of the codes are computed. Under the assumption that the encoding rules of the transmitter and the receiver are chosen according to a uniform probability distribution, the probabilities of success for different types of deceptions are also computed.
