- W813586698 abstract "Pervasive computing envisions an environment in which we are surrounded by many embedded computer devices. The existence of those networked devices provides us with a mobile, spontaneous and dynamic way to access various resources provided by different (security policy) domains. In recent years, we have witnessed the evolutionary development of numerous multiple domain applications. One of the richest examples is pervasive environments. Typically, the conventional approach to secure access over multiple domains is to implement a unique trusted infrastructure, extending local identity or capability based security systems and combining them with cross-domain authentication mechanisms. However, this does not adequately meet the security requirements of communicating with unknown players in pervasive environments. Moreover, it is infeasible to define a global trust infrastructure and a set of assumptions that every player will trust in the multiple domain context. A powerful design technique to address those new security challenges posed by pervasive environments is to understand them from a domain perspective. This thesis presents Localisation of Trust (LoT), an architectural framework designed to address the security need of how to talk to correct strangers in pervasive environments. Based on the localising trust security principle, LoT provides a generic platform for building access control over multiple domains from two ends: authentication and authorisation. Firstly, LoT proposes a two-channel authentication protocol to replace traditional (strong) identitybased authentication protocols by exploring desirable contextual information for different pervasive applications. Then, delegation and localised authentication are deployed to achieve authorisation in pervasive environments. The heart of this different semantic is to let the right domain get involved with its local players’ interactions by helping them to convert a “token” to a usable" @default.
