This scheme bearing the following characteristics : it provides mutual authentication between the user and server which can resist the impersonation attack; 本方案的特点是:提供了服务器和客户的双向认证,能够抵御假冒攻击;
It allows authorization data to be shared among virtual domains without the possibility of the impersonation attack. 该协议能够使虚拟域间在不受到假冒攻击的情况下共享授权数据。
In this paper, author makes use of symplectic geometry over finite field to construct Cartesian authentication code, presents a method of its construction, and at the same time, computes its size parameters and successful probability of impersonation attack and substitution attack. 本文利用有限域上辛几何构作了Cartesian认证码,给出了它的一个构造方法,计算了其容量参数、模仿攻击和替换攻击的成功概率。
Two constructions of Cartesian authentication codes from orthogonal geometry over finite field with characteristic 2 are given in this paper. Their size parameters and their probabilities of successful impersonation attack and of successful substitution attack are also computed. 利用有限域上偶特征正交几何构作了两个Cartesian认证码,并计算了它们的参数.还按均匀概率分布选取编码规则,计算了模仿攻击成功概率PI和替换攻击成功概率PS。
