Construction of Authentication Codes with Arbitration from Vector Space over Finite Fields

利用有限域上向量空间的子空间构作了一个具有仲裁的认证码,计算了这个码的参数。当收方和发方的编码规则按等概率分布选取时,各种攻击成功的概率也被算出。

A construction of authentication codes with arbitration from subspace of vector space over finite fields is presented, the parameters of the code are computed. Assuming that the encoding rules of the transmitter and the receiver are chosen according to a uniform probability distribution, the probabilities of deceptions are also computed.
