Diameter versus RADIUS Protocols

Paper Summary:

This paper explains the RADIUS protocol and how it accomplishes its three main objectives of providing authentication, authorization and accounting throughout WLANs configurations, ensuring their security in the process. The paper also discusses the transition from the RADIUS protocol to the Diameter protocol and the implications of using each protocol on network security.

Summary

From the Paper:

"The transition from the RADIUS protocol to the Diameter protocol has as it catalyst the greater flexibility and security the latter protocol provides, specifically over TCP and SCTP-based networks. The shortcomings of the RADIUS protocol are addressed in the design of the Diameter protocol, with specific attention paid to the need for higher levels of security and agility in defining network configurations. The implications for ISPs and those companies creating WLANs include greater support for wireless security configuration, and therefore greater flexibility and independence for their users in using their wireless and IEEE 802.11i devices on networks configured using the Diameter protocol."
