Research on the voting algorithm and its application in intrusion tolerant system

To solve the problems of Voting algorithm´s no output and no high accuracy, a voting algorithm based on testing information and historical record values has been designed. The algorithm can immediately extract services runtime error message from the memory and arithmetic logic unit and improve voting accuracy combined with the copy-computers´s recently history record values. The experiments prove that the improved voting algorithm has more accurate output than the effective weight voting which is based on a copy. It can provide continuous service, improve the integrity of the system and is more suitable for intrusion-tolerant system.
