Trust Model of Service Computing Based on Recommendation

Due to the openness and dynamic of Service Computing, more and more bad behaviors of malicious entities exist, and the traditional trust model can not adapt to the distributed, open and dynamic network environment, which severely endangers Service Computing network. This paper proposed a trust model of Service Computing based on recommendation, which includes the corresponding algorithms of its trustworthiness and integrated trust, and the punishment mechanism for vicious recommendation, drawing on the experience of the research of trust management concept and Beth trust model. Simulation results show that this model can assess the entities’ trust values more effectively, and the transaction success ratio surpasses the traditional trust management model.
