ontext-aware security and secure context-awareness in ubiquitous computing environments

Context-awareness emerges as an important element of future wireless systems. In particular, concepts like ambient intelligence and ubiquitous computing rely on context information in order to personalize services provided to their target users. However, security implications of employing context-awareness in computing systems are not well understood. Security challenges in context-aware systems include integrity, confidentiality and availability of context information, as well as target user's privacy. Another interesting and open question is to what extent availability of additional context information could be used in order to optimise and reconfigure security-related services
