Research on an algorithm with self-tolerant ability in hardware immune system

Research on hardware immune system is still in the initial stage. There are many problems to be solved, including how to avoid autoimmunization, etc.. A novel algorithm for the issue of autoimmunization was proposed, which was an inevitable problem when designing a hardware immune system. The algorithm endowed the hardware immune system with a certain extent of self-tolerance capability by deleting self-matching detectors according to co-stimulation. It increased the accuracy of detection and decreased the ratio of false positive. Results of simulation experiments proved the availability of the new algorithm.
