中文摘要:由于仅对通信报文关键信息进行单次加密，导致常规方法的防篡改效果不佳。因此，设计了基于CMS协议和混沌映射的继电保护通信报文安全防篡改方法。首先，对获取的通信报文信息进行滤波处理，提取出通信报文的关键信息，并分析其内部的关联规则；再根据通信报文关键信息的特点，生成对应的混沌映射函数，并利用该函数对通信报文关键信息进行初次加密处理；然后，在CMS协议的作用下，对其进行二次加密处理；最后，通过对通信报文信息进行解密，对其完整性进行验证，实现通信报文安全防篡改。实验结果表明，该方法在实际应用中的防篡改成功率较高，防篡改效果较好。

A Security and Tampering Prevention Method for Relay Protection Communication Messages Based on CMS Protocol and Chaos Mapping

Abstract:Due to only encrypting the key information of communication messages in a single attempt, the anti tampering effect of conventional methods is poor. Therefore, a secure and tamper proof method for relay protection communication messages based on CMS protocol and chaotic mapping was designed. Firstly, filter and process the obtained communication message information, then extract the key information of the communication message, and analyze its internal association rules. Based on the characteristics of the key information of the communication message, generate the corresponding chaotic mapping function, and use this function to encrypt the key information of the communication message for the first time. Under the action of the CMS protocol, encrypt it for the second time, and decrypt the communication message information, and verify its integrity to achieve secure and tamper proof communication messages. The experimental results show that the method has a high success rate in anti tampering and good anti tampering effect in practical applications.
