Random r-Continuous Matching Rule for Immune-BasedSecure Storage System

摘要

On the basis of analyzing demand of secure storage system, this paper use the artificialimmune algorithm to research access control system for the secure storage system. Firstlysome current matching rules are introduced and analyzed. Then the elements in immune-basedaccess 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 illegalaccess requests that one detector can check out. Implementing prototype of the random rcontinuousmatching 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 matchingrules. At last, we use the random r-continuous matching rule to realize immune-based accesscontrol system for OST in Lustre. Evaluating its I/O performance, the result shows its I/Operformance loss is below 8%, it proves that the random r-continuous matching rule can beused to realize the secure storage system that can keep high I/O performance.
