数据加密可以提高数据的传输安全。传统的数据加密方案基于链路层嵌入单向加密算法，无法有效解决加密独立分离和非线性加密问题。提出了一种基于高阶线性Riccati微分方程优化解的混合加密算法。设计了密钥扩展算法，利用高阶线性Riccati微分方程优化解的加密特性，得到加密过程中逆列混合变换，从而改进了混合加密的算法。仿真结果验证了该算法有效提高了数据加密解密性能，并具有较高的传输速率和极小的误码率，仿真结果表明其具有较好的应用价值。

Data encryption improves data transmission security. Traditional data encryption scheme using one-way encryp?tion algorithm for data link layer can’t effectively solve the encryption problem of separate and non linear.A hybrid encryp?tion algorithm is proposed based on higher order linear Riccati differential equation optimization solutions. The design of the key expansion algorithm and encryption scheme design through constructing high order linear Riccati differential equa?tions optimization solutions. Inverse Mix column transformation improved hybrid encryption. The simulation results show that the proposed algorithm can effectively improve the performance of encryption and decryption. It transmits information with higher rate and can restore the original source information with minimum bit error rate. The simulation results also show the application’s practical value.
