La sécurité des futures architectures convergentes pour des services personnalisés : aspect architectural et protocolaire

Abstract : The emergence and evolution of Next Generation Networks (NGN) have raised several challenges mainly in terms of heterogeneity, mobility and security. In fact, the user is able, in such environment, to have access to many networks, via multiple devices, with a vast choice of services offered by different providers. Furthermore, end-users claim to be constantly connected anywhere, anytime and anyhow. Besides, they want to have a secure access to their services through a dynamic, seamless and continuous session according to their preferences and the desired QoS. In this context, security represents an important concern. In fact, this user-centric session should obviously be secured. However, many challenges arise. In such environment, system boundaries, which were well delimited, become increasingly open. Indeed, there are multiple services which are unknown in advance and multiple communications between services and with users. Besides, heterogeneity of involved resources (terminals, networks and services) in the user session increases the complexity of security tasks. In addition, the different types of mobility (user, terminal, network and service mobility) affect the user-centric session that should be unique, secure and seamless and ensure continuity of services.
