Study of Network Authentication Security Mechanism Based on RADIUS Protocol

摘要

The security of the RADIUS protocol is the key problem for ensuring the AAA (Authentication Authority Accounting) function security in Internet. An improved RADIUS protocol based on HMAC-SHA1 using dynamic key is proposed to enhance the security performance of networks. Finally, through an AAA architecture setting up for the internet service provider, it has tested the performance and the function of the system. The test results show that The AAA architecture for the network streaming media video monitor system doesn't increase the complexity of the communication systems, and is simple and easy to implement
