Abstract
Systems and methods for providing efficient reputation management schemes resilient to malicious attacks. Methods for providing a reputation management scheme can comprise representing sets of service providers, raters, and ratings of service providers as a factor graph, wherein a factor node is associated with a function representing the probability distributions of the arguments of the function given the trustworthiness value and the ratings associated with a rater; and calculating the probability distributions of each variable in the reputation values of the set of providers using a belief propagation algorithm. In some embodiments, the computational complexity of the method is linear in the number of service providers and raters. In some embodiments, the method can identify malicious behavior and accordingly adjust the trustworthiness value for raters associated with malicious behavior.
