| Abstract: | An intrusion tolerance system that provides self-adaptation and recovery ability is built based on failure detector and diverse redundancy technology,proposing the architecture of the system,and designing the failure detector algorithm for the intrusion-tolerance system.This system can distinguish node-level and service-level failure,taking different shielding measures and recovery strategies assuring the system be reconfigured in time after being attacked and intruded.The result of experiment shows that the failure detector algorithm can solve the wrong judgement problem caused by network latency and packet loss.The accuracy of detection is clearly improved. |
