摘　　要：无条件安全通信系统利用信道的噪声特性,不需要像传统安全通信系统那样,必须有一个绝对安全的信道来进行密钥分发、密钥管理。秘密编码是无条件安全通信系统的关键技术,通过对最优检错码的二进制本原BCH码以及非最优检错码的二进制本原BCH码构造的秘密编码进行研究,给出秘密编码方法和秘密条件,最后进一步对其性能进行仿真,最终发现纠错编码中的最优检错码将是一类非常好的秘密编码,在无条件安全通信系统有很大的运用价值。Instead of pre-shared a secret key in traditional secure communication systems, the unconditional secure communication system takes the advantage of channel noise to build up the security, without any demand of a secure communication channel for distributing and managing the secret key. The secure coding is important to the unconditional secure communication system. In this paper, the secure codes constructed from the optical error-checking binary BCH code and the unoptical error-checking binary BCH code are discussed, and the encoding method and security condition also given. Simulation on the properties of the proposed security indicates that the optical error-checking binary BCH code is a very good secret coding, and thus of important value for the unconditional secure communication system.
