Abstract: New generation networks (NGN) use an IP base to transmit their services as well as voice, video and other services. The IP Multimedia Subsystem (IMS) which represents the network core, allowed controls and accesses into various services through a set of signalling protocols, the most common of which is Session Initiation Protocol (SIP). After securing the most vulnerable interfaces in the core of the NGN: IMS architecture. The idea is to improve QoS in SIP signalling, especially in authentication and registration that represent the first step to access. The proposed approach is used as encryption asymmetry in the SIP registration process and study the performance of the system in terms of QoS parameters.
