A New Trust Model Based on the Subjective Logic and Risk Mechanism for P2P Network
A novel trust model MR-TM which is based on the Multinomial Subjective Logic and risk mechanism is proposed to deal with the problems in P2P systems such as unreliability of the Service, security risk and attacks caused by malicious peers. The model bases on the Multinomial Subjective Logic theory, and introduced the risk mechanism. It assess and quantify the peers risk, through computing the resource value, vulnerability, threat level, and finally get the trust value by the risk value and the reputation value. The introducing of the risk value can reflect the recent behaviors of the peers better and make the system more sensitive to malicious acts. Finally, the effectiveness and feasibility of the model is illustrated by the simulation experiment designed with Peersim.
