Random r-continuous matching rule for immune-based secure storage system

Abstract

On the basis of analyzing demand of secure storage system, this paper use the artificial immune algorithm to research access control system for the secure storage system. Firstly some current matching rules are introduced and analyzed. Then the elements in immune-based access control system are defined. To improve the efficiency of the artificial immune algorithm, this paper proposes the random r-continuous matching rule, and analyze the number of illegal access requests that one detector can check out. Implementing prototype of the random r-continuous matching rule to evaluate and compare its performance with current matching rules. The result proves the random r-continuous matching rule is more efficient than current matching rules. At last, we use the random r-continuous matching rule to realize immune-based access control system for OST in Lustre. Evaluating its I/O performance, the result shows its I/O performance loss is below 8%, it proves that the random r-continuous matching rule can be used to realize the secure storage system that can keep high I/O performance. © 2009 Springer-Verlag Berlin Heidelberg.
