摘　　要：为了提高通信网络数据多信道传输的安全性,提出基于对称加密的通信网络数据多信道安全传输方法。建立通信网络数据多信道链路层分布结构模型,采用分段线性组合解码的方法进行通信网络数据多信道均衡控制。结合随机码幅度调制方法进行通信网络数据传输过程中的调制解调处理,使用对称加密算法进行通信网络数据加密的密钥设计。将算术编码嵌入到加密体系中,利用对称加密输出的比特序列进行循环移位处理,实现通信网络数据多信道安全传输。仿真结果表明,所提方法的泄漏概率为0.036,破译比特长度为1.46 kbit,识别度为97.54%,时间开销为0.54 s。采用所提方法进行通信网络数据多信道传输的安全加密性能较好,抗攻击能力较强。In order to improve the security of multi-channel transmission of communication network data, a multi-channel secure transmission method of communication network data based on symmetric encryption is proposed. The distributed structure model of multi-channel link layer of communication network data is established, and the piecewise linear combination decoding method is used for multi-channel equalization control of communication network data. Combined with the random code amplitude modulation method, the modulation and demodulation processing in the process of communication network data transmission is carried out, and the symmetric encryption algorithm is used to design the key of communication network data encryption. The arithmetic coding is embedded into the encryption system, and the bit sequence output by symmetric encryption is used for cyclic shift processing to realize the multi-channel secure transmission of communication network data. The simulation results show that the leakage probability of the proposed method is 0.036, the length of decoding bit is 1.46 Kbit, the recognition degree is 97.54%, and the time overhead is 0.54 s. The proposed method has good security encryption performance and strong anti attack ability for multi-channel transmission of communication network data.
