Dejiao Niu · 2008
On the basis of analyzing demand of storage security system and current artificial immune algorithm,this paper presents new artificial immune algorithm to ensure security of storage system efficiently.Main current matching rules are introduced to analyze the efficiency of current artificial immune algorithm.Firstly the structure of storage security system and the definition of main elements in it are given.To improve the efficiency of artificial immune algorithm,this paper proposes random r-continuous matching rule to improve the number of non-self that one detector can recognize.To avoid failure of storage secure system that no detector are self-tolerance and low efficiency of inspecting,this paper presents self-adaptable threshold selection algorithm to select suitable threshold for different detectors,and then balance between efficiency and accuracy for different self sets.Analyzing how much non-self one detector can recognize and whether the selection of threshold is adaptability.Using new artificial immune algorithm to implement the prototype of secure system and verify its performance.We implement prototype of new artificial immune algorithm.The evaluating result shows the new artificial immune algorithm has higher efficiency and is more adaptability than current artificial immune algorithm.At last,we modify the source code of storage area network system named Lustre and implement prototype of the secure disk system.By evaluating its I/O performance,the result shows new artificial immune algorithm can ensure the security of storage efficiently.
