Subscriber Privacy in Cellular Systems
Geir M. Køien · 2007
In this article we analyze the standard 3G access security architecture. We then propose new requirements that strengthen the security and improve the subscriber privacy. To achieve enhanced subscriber privacy the subscriber identity presentation scheme has been modified. Satisfactory performance is a decisive factor in any real-world system, and the design of the new protocol combines selected Mobility Management signaling sequences with the Authentication and Key Agreement (AKA) protocol to achieve a fast setup. The PE3WAKA protocol presented here belongs to a family of protocols. The other family members are presented and discussed in [1-3].
