摘要
Abstract
The existing methods have the problem that the average response time of substation system database access is long,hence,and a tamper-proof method for real-time monitoring database of intelligent substation operation and maintenance system is proposed.The watermark is divided into multiple watermark information,the watermark capacity and MD5 value are calcu-lated,and the database embedded watermark encryption function is designed to complete the database encryption.We calculate the correlation between the inverse transform encryption response function and the embedded watermark sequence,extract the embedded watermark,recover the tampered data of the database,and realize the real-time monitoring database tamper proof of the intelligent substation operation and maintenance system.The experimental results show that the database encryption speed is significantly improved under the proposed method.关键词
