The Next Generation Network (NGN) is an IP-based, packet-oriented telecommunications architecture designed to support a wide range of services. The IP Multimedia Subsystem (IMS), in comparison, provides the control layer and service delivery framework that enables multimedia applications to function over NGN. While NGN constitutes the core network infrastructure, IMS serves as the specialized platform responsible for delivering and managing multimedia services such as voice and video communications to end users. Security for users, services, and providers is a fundamental requirement. The growing sophistication of security threats, combined with service diversity and the widespread adoption of cloud-based and distributed systems, has made comprehensive security a primary concern. In this work, a holistic security mechanism is introduced to improve protection across the IMS environment by integrating IMS architecture with cloud computing platforms. This integration leverages the cloud's advanced security capabilities, multiple deldiveeferynseframlayeewros,rkanthdatcoanlltorwols mopeecrhaatnoirssmtso tooffer strengthen system reliability, confidentiality, and overalaldrovabnucsetndeNssG.

As shown in Figure 1, the This paper presents an integration between two fields: telecommunication services and network concepts along with open technologies, aiming to provide an open service creation framework and to leverage the security mechanisms offered by cloud-based authentication.
