Secured Agile Architecture for Context Aware Pervasive Computing

Free registration required

Executive Summary

Context refers to information such as location, time, user preferences, user emotions, environment status, computational devices and network parameters, etc. Context-aware pervasive computing utilizes the information about the physical world collected form various sensors and changes the behavior automatically considering current context, history and other user preferences. The context viewed or used by pervasive systems may change mobility or characteristics of that particular device. Access of certain information may be restricted to a particular security level to protect information from tampering. Security contexts enhance the security in context-aware pervasive systems which are nothing but collection of user's information which is applicable to available security policies. Traditional security models aim to provide integrity, confidentiality and availability of information.
