Research on Field Bus Channel Encryption Method for Water Conservancy Automation Control System Based on Domestic Password

针对水利自动化控制系统现场总线信道加密的局限,提出基于国产密码的水利自动化控制系统现场总线信道加密方法研究。通过选用国产密码并采用组合方式,克服了加密范围的限制,提高了加密速率,构建的加密模型通过解密验证实现高效加密。测试结果表明:相较于传统方法,此次所设计的国产密码水利自动化控制系统现场总线信道加密方法的加密速率更高,效果更佳,具有实际应用价值。

Aiming at the limitations of ficld bus channel encryption in water conservancy automation control systems,a research on ficld bus channel encryption method based on domestic passwords is proposed.By using domestically produced passwords and combining them,the limitations of the encryption range have been overcome,and the encryption rate has been improved.The constructed encryption model achieves efficient cncryption through dccryption verification.The test results show that compared to traditional methods,the encryption rate of the ficld bus channel encryption method for the domestically designed password water conservancy automation control system is higher and the effect is better,which has practical application value.
