摘要
基于智能磁盘的安全存储设备是当前安全存储系统研究的热点问题。为解决现有安全存储设备I/O性能低的问题,引入人工免疫算法,实现高效的访问控制模块。首先给出基于免疫安全存储设备的结构,以及基于免疫访问控制模块中主要元素的定义,针对存储设备的特点,设计了差异选择算法和混合检测算法。实现了基于免疫访问控制的原型系统,验证了系统能高效地识别非法数据访问请求。修改开源存储区域网系统-Lustre中智能磁盘模块的代码,构建基于免疫安全存储设备的原型系统,测试了I/O性能。结果验证了基于免疫安全存储设备的I/O损失较小,能构成较高性能的安全存储系统。
The secure storage device is a hot topic in current secure storage system researching. In order to improve the I/O performance of current secure storage device,we used artificial immune algorithm to research efficient access control system for it. The structure of immune based secure storage device and some definitions of element in immune based access control system were given. By analyzing the characters of secure storage device,we presented diversity selection algorithm and mixed checking algorithm. Realizing the prototype of immune based access control system and testing the efficiency of it, the result shows it can inspect illegal access request efficiently. Realizing the prototype of immune based secure storage device in Lustre and evaluating its I/O performance. The result proves that the immune based secure storage device has high I/O performance and can be used for efficient secure storage system.
