摘　　要：研究有限局部环上的线性认证码。线性需要认证码具有附加的代数性质,当密钥、报文和攻击概率给定时,计算信源的上界,给出线性认证码在构造带仲裁认证码中的应用。Linear authentication codes over finite local rings are considered. Linearity requires some additional algebraic properties for the A-codes. When the sizes of the key space, the authenticator space, and the deception probability are fixed, an upper bound on the size of source space is computed. It is al- so given an application about linear authentication codes in constructing authentication codes with arbitra- tion.

关 键 词：有限局部环 无条件安全认证码 线性认证码
