Executive Summary

Next Generation Network (NGN) focuses on improving the telecommunication core and access networks and plans to transport all the services by encapsulating them into packets via a single IP based network. NGN provides various types of multimedia services which will be fully ready for use in coming few years. These services include presence, messaging, push to talk over cellular, multiparty conference etc. These NGN multimedia services are subject to various types of security flaws related to authentication of the users, denial of service, data integrity, privacy and confidentiality etc. Moreover provision of Quality of Service (QoS) (resource utilization, delay minimization etc.) is also a major challenge to these services for gaining success.

The project aims to develop a framework that on one side improves the security of these services by providing data integrity, privacy and confidentiality solutions against various types of attacks while on the other side makes these services more efficient by modifying the existing session setup, registration, service creation and service subscription procedures. Inclusion of new value added features in these multimedia services is also the part of the proposed research work. This work will help these services to gain the confidence of the business sector and the potential users and will play a vital role in the success of NGN.
