摘　　要：随机码信息加密是保障信息通信安全的基础,传统的随机码信息加密算法采用高阶线性微分解优化的混合加密算法,密钥扩展过程中,链路层加密数据出现非线性突变,采用任何一轮子密钥即可破解全部密钥,加密性能不好。提出一种基于随机码幅度调制的双线程互补信息加密算法。分析了加密信息通信系统的随机编码序列发生原理,进行密钥设计,生成的随机数对信源发出信源密钥,加密序列按位异或运算进行双线程信息互补编码和解码,采用随机码幅度调制生产信息加密密钥,实现加密算法改进,仿真结果表明,采用该算法进行信息加密,有效降低了对方信息系统对密码的识别率,难以被攻击系统检测识别,提高信息安全性。Random code information encryption is the basis of the security of information security. Traditional random code information encryption algorithm using high order linear micro decomposition optimization of hybrid encryption algorithm, the key expansion process, link layer encrypting data nonlinear mutation, through all the affine transform any wheel key can crack the secret keys, encryption performance bad. A double thread complementary information encryption algorithm based on the amplitude modulation of random codes is proposed. Analysis of the random coding sequence encryption of informa-tion and communication system principle and key design, generate random number source of a source key and encryption sequence the bitwise XOR operation of double thread information complementary encoding and decoding, using random code amplitude modulation production information and decryption key, the encryption algorithm to achieve improved. Simu-lation results show that using this algorithm to encrypt information and the other information systems of password recogni-tion rate is effectively reduced, is difficult to attack detection and recognition system, improve the safety of information.
