The encryption method of sampled data in power system based on energy storage technology

针对传统电力系统采样数据加密方法的密文解析正确率较低的问题,文中提出并设计一种基于储能技术的电力系统采样数据加密方法。首先建立安全防护C/S体系架构,结合多层次的安全管理体系,补充管理信息数据库的信息节点,完成电力系统安全防护体系的建立;然后引入3DES加密算法,根据标度赋值平衡两个因素之间权重,增加数据保密性,利用嵌入式终端辅助解密,对其中的加密扩展卡进行设计,提高数据的解密正确率。通过实验结果表明,设计方法的解密结果的解析正确率较高,验证了设计方法在提高密文解析正确率方面的有效性。

In view of the low accuracy of ciphertext analysis in the traditional power system sampling data encryption method,a power system sampling data encryption method based on energy storage technology is proposed.Firstly,the C/S system architecture of security protection is established,combined with multi-level security management system,and the information nodes of management information database are supplemented to complete the establishment of power system security protection system.Then the 3DES encryption algorithm is introduced to balance the weight between the two factors according to the scale assignment,the data confidentiality is increased,the embedded terminal is used to assist the decryption,the encryption expansion card is designed,and the decryption accuracy of the data is improved.The experimental results show that the decryption result of the design method has a higher resolution accuracy,which verifies the effectiveness of the design method in improving the resolution accuracy of ciphertext.
