Fuzzy Amendments of Trust Model with Intrusion Tolerance

Abstract

When the topology of data network in power grid was destroy, the system still need to provide intrusion tolerance service. The trust values relationship of the nodes in data network need be calculated. The trust value of the upper and lower limit can be deduced and adjusted to eliminate the problem of over-reliance on threshold. And the introduction of confidence values to assess the quality of the trust value. A recursive algorithm is used to obtain the average of the trust data to compute confidence values. The experimental result proves the veracity and validity of the method.
