Generalized Analysis of Convergence of Absolute Trust in Peer to Peer Networks

Open and anonymous nature of peer-to-peer networks provides an opportunity for malicious peers to behave unpredictably in the network. This leads to lack of trust among peers. To control the behavior of peers in the network, a reputation system can be used. In the reputation system, aggregation of trust is a primary issue. Algorithm for aggregation of trust should be designed, such that it can converge to a certain finite value. Absolute Trust is one such trust aggregation algorithm. This letter presents the generalized analysis of convergence of the Absolute Trust algorithm.
