CONSTRUCTION OF AUTHENTICATION CODES WITH ARBITRATION FROM UNITARY GEOMETRY

A family of authentication codes with arbitration is constructed from unitary geometry,the parameters and the probabilities of deceptions of the codes are also computed.In a special case a perfect authentication code with arbitration is obtained.

利用酉几何进一步构造带仲裁的认证码

该文利用有限域上的酉几何构作了三类新的带仲裁的认证码,计算了码的参数;当编码规则按等概率分布选取时,计算出各种攻击成功的概率。研究结果表明可用酉几何进一步构作多类带仲裁的认证码。
