Secure service provisioning framework (SSPF) for IP multimedia systems and next generation mobile networks

The objective of this paper is to propose Secure Service Provisioning Framework (SSPF) providing security association, security architecture and protocols for IP Multimedia Systems and Next Generation Mobile Networks. The security features to accomplish in securing access to the IMS are to protect SIP signalling, authentication and key agreement, network domain security and trusted domain establishment through policy based security associations. The IMS security based on Authentication & Key Agreement, Network Domain Security, and IMS Access Security for SIP-based and HTTP-based services. An independent IMS secure service provisioning framework provides additional protection against security breaches e.g. if the PS domain security is breached the IMS would continue to be protected by its own security mechanisms.
