A Context-Based Approach of Security Policies
Ghita Kouadri Mostéfaoui, Patrick Brézillon · 2004
The wide adoption of handled devices and remote ser-vices arises a number of security problems for users and services providers. The ubiquitous (pervasive) nature of such applications has brought new security vulnerabil-ities, and security in pervasive computing is thus, still a hot topic. Context-based security is an emerging ap-proach for modeling adaptive security solutions based on the context of use of the system. Our contribution aims at presenting a new model for specifying context-based security levels. This approach is based on contex-tual graphs and relies on a set of contextual information collected from the system and user’s environments.
