电子信息保密通信传输链加密方法改进研究

Research on Improvement of Encryption Method for Electronic Information Secret Communication Transmission Chain

在目前的电子信息保密通信传输链加密工作中,常常使用电路混沌作为数据加密法,但电路混沌对电路高衰变存在限制,在通信传输中存在吞吐量不足问题。因此提出新的电子信息保密通信传输链加密方法。首先定义完美保密性,通过加密密钥完成信息保密,同时采用半导体激光器来代替传统电路混沌,建立激光混沌模型,实现电子信息保密通信传输链的加密。为验证改进方法的有效性,设计仿真实验,在不同的发射功率和保密中断概率下对比不同方法加密性能。实验结果得出,所提方法吞吐量更多,性能更好,具有应用有效性。

In the current electronic information security communication transmission chain encryption work,circuit chaos is often used as data encryption method,but circuit chaos has limitations on the high decay of the circuit,and there is a problem of insufficient throughput in communication transmission.Therefore,a new encryption method of electronic information confidential communication transmission chain is proposed.First,define perfect confidentiality,complete information confidentiality through encryption keys,and use semiconductor lasers to replace traditional circuit chaos,establish a laser chaos model,and realize the encryption of electronic information confidential communication transmission chain.In order to verify the effectiveness of the improved method,a simulation experiment was designed to compare the encryption performance of different methods under different transmission power and security interruption probability.The experimental results show that the proposed method has more throughput,better performance and application validity.
