Research on information security algorithm based on data mining

新型电力系统具有智能性和通信速度快的特点,在电网数据传输过程中需要对数据与信息的安全进行保护。针对这一问题,文中设计了一套电网数据保护算法。由于用户的用电数据包含各类敏感信息,因此该算法主要在智能电表终端利用蜂窝网络将用户用电数据上传至服务器时进行保护。算法在对用电数据进行采集的过程中,同时建立了终端匿名组。通过Paillier加密算法对计量数据进行加密并签名,以完成对数据的保护。实验结果表明,与同类算法相比,文中算法对长短密钥的加密、解密速度均为最优,且可以抵御恶意攻击,证明了所提算法应用在电网信息保护系统中,能够有效防止用户数据泄露。

Thenew power system has the characteristics of intelligence and fast communication speed. It is necessary to protect the security of data and information in the process of power grid data transmission.To solve this problem,a set of power grid data protection algorithm is designed in this paper. Because the user’s power consumption data contains all kinds of sensitive information,the algorithm mainly protects the user’s power consumption data when the smart meter terminal uploads the user’s power consumption data to the server through the cellular network. In the process of collecting power consumption data,the algorithm establishes a terminal anonymous group,encrypts and signs the metering data through Paillier encryption algorithm to complete the data protection. The experimental results show that compared with similar algorithms,the proposed algorithm has the best encryption and decryption speed in both long and short keys,and can resist malicious attacks. It is proved that the proposed algorithm can be applied to the power grid information protection system to effectively prevent user data leakage.
