Identity The process of authentication (authentication techniques are totally different and varies in pervasive computing) involves collecting evidence about the identity of users The information of both trust and context are highly considered in the process of authentication, because they give an insight view into user’s identity The concerns of identity in pervasive computing are much bigger than in other... arguments for the conditions of the situation of any subject or target, which influences their interactive behaviour Privacy, security and trust may hence be representative of the rules that influence the interactive behaviour between a subject and a target, or the post-assertion of the validity of the interaction and resultant context Context is therefore the knowledgebase that supports the reliable... much easier in comparison to the situations of no prior information This is why some of the proposed trust management systems incorporate solutions for uncertainty There are some other factors that influence greatly the establishment of trust, namely contextual information about the interaction, and privacy concerns The combination of the trust reasoning and other factors (context and privacy) will help...

The State of the Art in Pervasive Computing The term Pervasive Computing emerged from research at IBM dur- ing 1996 - 97, embracing the vision of computing. trusting the context as opposed to trusting a person or thing. The assurance of security within a context has then been identified as a prop- erty in the function of trusting the context. Furthermore,
