Abstract:
Next Generation Networks (NGN) are packet-switched telecommunications architectures that rely on IP technology to support a broad range of services. In contrast, the IP Multimedia Subsystem (IMS) functions as the control and service framework that allows multimedia applications to operate over NGN. In simple terms, NGN provides the underlying network infrastructure, while IMS acts as the platform within that infrastructure that manages multimedia services such as voice and video communication for end users. Ensuring security for users, services, and providers is a critical priority. The increasing complexity of cyber threats, the wide variety of services, and the extensive use of distributed cloud environments make comprehensive security more important than ever. This paper proposes an integrated security mechanism aimed at strengthening protection for users, services, and providers within the IMS framework by tightly integrating IMS architecture with cloud computing environments. By leveraging multiple advanced security features, layered protection strategies, and control mechanisms inherent in cloud computing, the proposed approach enhances the system’s overall reliability, confidentiality, and resilience. 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, but not discuss the impact of the security mechanisms implementation to the QoS, latency, throughput.
Keywords: IMS, Cloud Computing, OpenStack, Security, SIP.
