A trust evaluation and recommendation algorithm based on Internetware

Internetware is endowed with more flexibility in the dynamic, open network. However, it is facing a big challenge in trust evaluation on interaction between two components. This paper proposes an effective way of trust evaluation based on the punishment mechanism and proved its function to resist malicious attack. As trust relationships can be obtained by the recommendations of other Internetwares, thus a virtual trust information network naturally formed. In this way, the trust relationship of an Internetware can be derived without direct interaction. However, the problem lies in we might get malicious information and be led to misjudgment in such a complex and changeable network. Therefore, we put forward an algorithm based on the idea of RIP routing algorithm. The algorithm is proved to be efficient and reliable through experiment.
