【摘要】 引入I-t-分裂认证码的概念。由有分裂的认证码得到纠错码,说明了当替换攻击成功的极大概率等于冒充攻击成功的极大概率时,信源数随编码规则数增大成线性增加,这一结论在无分裂认证码的情况下也成立。更多还原

【Abstract】 The concept of I-t-spliting authentication codes is proposed. The error-correcting codes can be got from the authentication codes with spliting. When the maximal probability of the success for the substitution attack is equal to that of the impersonation attack , the number of the resourse states grows linearily with the number of encoding rules. This result is also true for that of the authentication codes without spliting.更多还原
