分布式多信任域信任管理技术研究综述

随着Internet技术的迅速发展和广泛应用，出现了基于Internet虚拟社会，如P2P、网格、无线网络、多代理网络、无线传感器网络等，从而引起了信任概念从人类交互世界向虚拟交互世界的迁移。近年来研究者针对虚拟交互世界提出了各种信任管理模型，这些模型的多样性使得在实际应用中会产生多种信任域。一些文献提出了如何实现多信任域中代理间的可信交互。分析了多信任域的相关概念及其产生的原因，对选取新的典型的多信任域信任管理模型及其使用的各种方法进行了评述;分析了目前研究中存在的问题，并展望了未来的发展方向。研究表明，多信任域中代理间的可信交互是目前信任管理中的难点问题。

Survey of Trust Management in Distributed Multi Trust Domain

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.
