嵌入式实时数据库的安全缓冲区管理器的设计

Design of security buffer management on embedded real-time database

分析嵌入式实时数据库安全缓冲管理算法SABRE,将其引入到开源数据库Berkeley DB的缓冲中,设计实时安全缓冲区管理器。一般实时数据库的缓冲区管理都基于优先级,在设计中将安全级别与优先级结合,构成综合优先级,可以根据系统的安全要求和实时特征动态调整权值以适应不同的要求,既满足实时也满足安全。主要有两种数据结构:安全级别队列数组和优先级队列数组。

The secure buffering algorithm used in embedded real-time database is analyzed, and the idea is used to the buffer management of open source embedded database Berkeley DB and a security buffer management is designed. The buffers of real-time database are usually based on priority, combine the security level and priority to an integrated priority in our design, dynamically adjust weights based on the requirement of security and real-time, satisfy real-time also security. There are two major data structure： Array of security- level queue and array of priority queue.
