Abstract :
This paper firstly gives security analysis for current AAA architecture, and presents an optimal AAA key agreement mechanism based on XTR algorithm, including three kinds of keys in different domains and anonymous identity verification mechanism to ensure communication security between Pac and NAS. Final test for the comparison with common algorithm in AAA application proves that the optimal algorithm can not only improve run speed, but also reduce the cost.
