随着智能电网的信息化和工业化的逐步融合,为了保证了传送数据的完整性以及通信系统的安全性,采用动态秘密的对称密钥算法,对智能电网安全进行设计,设计了有效序列模块、对称密钥模块、数据加解密模块、消息摘要设计计算模块。研究得出:确保通信设备的合法的情况下,对动态秘密的对称密钥进行改进,该算法不依赖于数据链路层协议与网络状态,从而有效解决了传统密钥的管理问题,确保了密钥的新鲜性与随机性,提高了通信效率和数据的安全性,从而有效解决了电网系统面临着数据窃听,恶意设备接入、篡改等威胁。

With the gradual integration of information technology and industrialization of intelligent power grid,in order to ensure the integrity of the transmission data and the security of the communication system,the dynamic secret symmetric key algorithm was used to design the intelligent grid security and design the effective sequence module,symmetric key module,data encryption and decryption module,and message digest design calculation module.It was concluded that the symmetric key of dynamic secret was improved when the communication device was legal.The algorithm does not depend on the data link layer protocol network status,which effectively solved the traditional key management issues to ensure that the key of the freshness and randomness,improved the communication efficiency and data security,so as to effectively solve the power grid system that was facing data eavesdropping,malicious equipment then Into,tampering and other threats.
