Developing P2P Trust Computing Mechanism based on Risk Evaluation Properties

摘要：

Risk is associated with almost every activity that is done in trust computing. Analyzing the Risk involved in a trust computing is important to decide whether to proceed with the transaction or not. In this paper, SMT, a trust computing mechanism is proposed for large-scale PZP systems based on risk evaluating properties. SMT incorporates two risk evaluating properties to reflect the dynamic trust relationship between peers. Meanwhile, in order to get quick computational convergence, SMT uses simple but effective mathematical formulas to establish trustworthiness aggregation algorithm Third, SMT uses a integrated global reputation mechanism which has good scalability for large-scale P2P systems. Simulations results show that, compared to the existing trust mechanisms, the new mechanism has remarkable enhancements in the trust decisionmaking accuracy and has a better dynamic adaptation capability.
