Abstract
AAA(Authentication, Authorization, Accounting) protocol is a framework that propose functions of AAA on multiple networks and platforms. AAA protocol is extending from previous RADIUS protocol to Diameter protocol. There are some Diameter applications for variety purpose. Diameter CMS Application makes Diameter messages more secure by using PKI. Diameter CMS Application establish DSA(Diameter Security Association) for end to end security. However the Application has some problems to establish DSA(Diameter Security Association), which can make Diameter system unstable. If one system lose DSA information for some system error - for example, reboot -, the secure communication between two nodes may not be possible. At the application such as MIP, even user registration can't be done. In this paper, we propose a mechannism for DSA re-establishment, and also show the result of the implementation.
