- Abstract
- This paper mainly focuses on improving NGN authentication performance and security to reduce the critical IMS service authentication procedure with redundant reduction in fixed and mobile networks. In the NGN specifications, authentication is performed at both the NASS and the IMS networks before a user equipment can access the IMS services. Though the NACF-IMS bundled authentication was proposed for this purpose, it cannot protect authentication procedure against IP address spoofing attack and channel between a user equipment and P-CSC-FE due to an absence of key sharing method. We observe that many steps in this two-pass authentication are similar. Based on our observation, this paper proposes an one-pass authentication procedure that only needs to perform NACF authentication. At the IMS service level, authentication is implicitly performed in IMS registration for NGN networks. Simulation results demonstrate that the proposed scheme provides better reduction of authentication procedure and performance for arrival rates with NGN environments than other methods.
