Survey of Trust Management in Distributed Multi Trust Domain
分布式多信任域信任管理技术研究综述

With the rapid development and extensive application of Internet technology, emergence of Internet based virtual community, such as P2P, Urid, wireless networks, multi-agent networks, wireless sensor networks, has caused the migration of reputation related concepts from the world of human interactions to the world of virtual interactions. In recent years, researchers have proposed various trust management models for virtual interactive world, such diversity of trust management model will bring multi trust domains in the different application environments. Some papers have proposed how to achieve trusted interactions between multi domain agents.The interrelated concepts and reasons of multi trust domain were summarized and presented. Several typical trust management systems of multi trust domain including their various methods were described in detail. The current problems and the challenges of this field for future research were presented.The research work indicates that the trusted interactions between multi domain agents create the biggest challenge in the trust management.
