在伪辛几何上构作新的带仲裁认证码

New construction of authentication codes with arbitration form based on pseudo-symplectic geometry

针对具有仲裁的认证码既能防止敌手的欺骗,又能防止收方和发方的互相欺骗的特点,利用伪辛几何构作了一类新的具有仲裁的认证码,并计算其参数.在假定源状态和编码规则都是等概率分布选取时,计算其各种攻击成功的概率.

Unconditionally secure authentication codes with arbitration protect against deception from the transmitter or the receiver as well as against fraud from the opponents. A new construction of authentication codes with arbitration form based on pseudo-symplectic geometry is given, and their parameters are computed. Assuming that the probability distributions of source state and encoding rules are uniform, the probabilities of all successful attacks are also computed.
