摘　　要：数据库中存储着大量的敏感数据,而无人值守能源平台通常需要通过公共网络进行数据传输和远程访问,这增加了被黑客攻击的风险。针对无人值守能源平台信息存储过程中可能受到安全威胁的问题,提出无人值守能源平台数据库信息安全存储算法。根据按需压缩思想建立自适应压缩算法,计算采样时段内能源平台数据变化量均值,以判定采样频率的变化情况。引入A^(*)算法寻优采样频率,自适应采集并压缩能源平台数据。结合动态密钥选择技术和混沌加密算法构建双重加密算法,用于数据库信息的加密,保障能源平台数据库信息的安全。通过使用强度和带宽占用概率控制超带宽存储并依据最小传输粒度控制超带宽梯度传输,实现无人值守能源平台数据库信息安全存储。实验结果表明,所提算法存储安全性高、存储耗时短、通信开支低和读写平均延迟短,且数据完整性高。Due to the large amount of sensitive data stored in the database and the fact that unattended energy platform typically require data transmission and remote access through public networks,this increases the risk of being attacked by hackers.Aiming at the potential security threats during the information storage process of unattended energy platform,a database information security storage algorithm for unattended energy platform is proposed.Based on the concept of on-demand compression,an adaptive compression algorithm is established to calculate the energy platform data change mean during the sampling period,in order to determine the change in sampling frequency.This paper introduce the A^(*)algorithm to optimize sampling frequency and adaptively collect and compress energy platform data.Combining dynamic key selection technology and chaotic encryption algorithm,This paper construct a dual encryption algorithm for encrypting database information which ensures the security of energy platform database information.By using strength and bandwidth occupancy probability to control ultra bandwidth storage and controlling ultra bandwidth gradient transmission based on minimum transmission granularity,the security storage of unattended energy platform database information is achieved.The experimental results show that the proposed algorithm has high storage security,short storage time,low communication cost,short average read and write delay,as well as high data integrity.
