A Multi-authentication Architecture Based on DIAMETER

Comparing two AAA protocols, the authors find that the compatibility of the DIAMETER protocol is better and more advanced than that of the RADIUS protocol. The authors design a security model based on this protocol to conduct network management. The principle of this model is to use the extended features of EAP to force users to update the OS and the virus feature library. Using this model to implement network management can reduce objective threats of end users, reduce spam traffic, increase the payload of the network, and enhance the security of the network
