摘　　要：在数据传输过程中,不同层级之间存在差分值作用,使得数据的安全性难以得到保障,因而提出了安全约束下嵌入式终端数据分层传输同步加密算法,即将结合明文数据在各层级之间的输出值计算出分层传输数据差分信息作为密钥的比特值,通过变换操作构建加密密钥,在数据传输的各层级设置计数器,确认传输器和嵌入式终端之间的一对一关系后,将统计到的加密解密次数作为密钥应用次数的设置值,实现密钥的同步。仿真测试结果表明,设计方法加密后浮点数高于另外2种对比方法,且密钥的随机性更高,具有更高的安全性。In the process of data transmission,the differential value between different levels acts to make the security of data difficult to be guaranteed.Therefore,a synchronous encryption algorithm for hierarchical transmission of embedded terminal data under security constraints is proposed,i.e.,calculating the hierarchical transmission data differential information as the bit value of the key by combining the output value of plaintext data between each level,constructing the encryption key by transformation operation,after confirming the one-to-one relationship between the transmitter and the embedded terminal,the counted number of encryptions and decryptions are used as the set value of the number of key applications to realize the synchronization of keys.Simulation test results show that the designed method encrypts a higher number of floating points than the other 2 compared methods,and the randomness of the key is higher and has higher security.
