基于非线性函数构造了一类新的认证码,计算出了该认证码替换攻击成功的概率和模仿攻击成功的概率,并与前人所做的认证码进行了比较,分析了所构造认证码的优缺点。
A new class of authentication codes using functions with nonlinearity is constructed. It is calculated the probability of successful impersonation attack and the probability of successful substitution attack, and we compare them with the known codes. We also analyze advantages and disadvantages of the new class of authentication codes.
