摘要
嵌入式设备通常运行在不可信环境中,由于数据库有限,一旦带宽失去控制,导致存储过程受到溢出攻击,降低存储安全。为此,提出一种针对嵌入式ARM平台的数据库信息安全存储算法。搭建数据库,并设计最优数据采样频率方法。然后,构建双重加密算法,使用强度和带宽占用概率控制超带宽存储,并基于最小传输粒度控制超带宽梯度传输,实现信息安全存储。实验结果表明,所提方法的信息存储安全性始终高于95%、存储耗时低于10ms、通信开支在25kB左右、读写延迟低,有效提高了电力系统的安全存储能力。
Embedded devices typically run in unreliable environments with limited databases.Once the bandwidth is out of control,it can lead to overflow attacks on stored procedures,therefore reducing storage security.Thus,a database information secure storage algorithm for embedded ARM platforms is proposed.A database is built and the optimal data sampling frequency method is designed.Then,a dual encryption algorithm is constructed which uses strength and bandwidth occupancy probability to control ultra bandwidth storage,and controls ultra bandwidth gradient transmission based on minimum transmission granularity to achieve secure information storage.The experiment results show that the information storage security of the proposed method is always above 95%,the storage time is less than 10ms,the communication cost is around 25kB,and the read and write latency is low,effectively improving the secure storage capacity of the power system.
