Context-awareness security model based on multi-agents system operating in complex environment

Abstract

In complex and pervasive environments, characterized by frequent and unpredictable changes, privacy and security are the most challenging tasks due to their importance and sensibility. Traditional Schemes of security seems inadequate for these novel challenges. The consideration of the execution context represents a key element for the efficiency of the security policies face to these circumstances. In other words, the system must be context-aware. This paper aims to respond to these novel challenges, by proposing a security policy, based on the `context-aware' notion. The system is conceived as a multi-agents system. The latter is chosen since its mobility and autonomy properties facilitate the achievement of desired objectives. Furthermore, the use of ontology permits to increase the objectivity and eliminate the eventual semantic heterogeneities. The paper presents firstly the general architecture before detailing each one of its components, as well as the distinguished consideration of the context-aware and semantic aspects.
