摘  要:
普适计算中开放的动态环境提升了安全和信任管理的挑战,没有信任,普适设备就不能有效地协作,而普适计算也就只能局限于某些特定的领域。传统的集中的安全管理模型不能直接应用于普适计算环境中。现存的用户认证和控制管理同样不再适用。为了克服集中式模型的限制,在普适计算环境中,需要采用分布式的解决方法,对几种分布式的信任模型进行了详细的分析与比较。

摘  要:
Pervasive computing allows a seamless interaction among users,devices,and applications anytime and anywhere.Yet portable devices in pervasive computing are mainly powered by batteries and have limited computational and communication capability.The open and dynamic environment in pervasive computing poses challenges in security and trust management.Without trust,pervasive devices cannot cooperate effectively,and the deployment of pervasive computing systems will be restricted to specific application scenarios.The traditional centralized security management schemes are not directly applied in pervasive computing environments.Moreover,existing user authentication and access control schemes are inadequate to ensure security in pervasive computing.Distributed solutions can be used in pervasive computing environment to overcome the limitation of centralized schemes.Several kinds of distributed trust management schemes are analyzed and compared in detail.
