Research on optical fiber communication encryption in underlying difference module of the Internet of things

为了提高光纤通信的加密隐写性能,提出一种基于随机关联映射编码体制的物联网底层差异模块光纤通信加密算法。构建混沌密钥状态特征方程,把物联网底层差异模块的大数据加载到混沌密钥状态特征方程中,得到一组描述密钥域信息熵的特征解,进行椭圆曲线随机编码设计和混沌编码配置,采用光纤通信隐私保护方法进行信息多层加密译码隐写,在双线性映射编码体系下实现物联网底层差异模块光纤加密隐写和保密存储及传输。仿真结果表明,没有干扰下,加密耗时仅为2.01 s,加密精度达到了0.92,自适应转发准确率为0.96;加密带有一定干扰的数据时,所提方法的加密耗时仅为3.23 s,加密精度可达到0.83,自适应转发准确率为0.91。光纤通信信息多层加密的隐写性能较好,其准确性较高且加密耗时较少。

In order to improve the encryption steganography performance of optical fiber communication,a fiber communication encryption algorithm based on underlying difference module of the Internet of things in random association mapping coding system is proposed.The chaotic key state characteristic equation is constructed,and the big data of underlying difference module of the Internet of things is loaded into the chaotic key state characteristic equation,and a set of characteristic solutions describing the information entropy of key domain are obtained.The simulation results show that,without interference,the encryption time is only 2.01 s,the encryption accuracy reaches 0.92,and the adaptive forwarding accuracy is 0.96.When encrypting data with a certain interference,the encryption time of the method in this paper is only 3.23 s.The encryption accuracy can reach 0.83,and the adaptive forwarding accuracy is 0.91.The multi-layer encryption of optical fiber communication information has better steganography performance,its accuracy is higher,and the encryption takes less time.
