4.4.4 RADIUS
Managing a large number of users creates the need for significant administrative
support together with careful attention to security, authorization and accounting.
The use of RADIUS (Remote Authentication Dial In User Service) enables
operators to manage a single database of users, supporting authentication
(verifying user name and password) as well as configuration information detailing
the type of service to deliver to the user and the traffic that the user transmitted
and received, for billing proposes.
RADIUS is a protocol for carrying authentication, authorization, and configuration
information between a Network Access Server (NAS), which desires to
authenticate its links, and a shared Authentication server. A Network Access
Server operates as a client of RADIUS. The client is responsible for passing user
information to designated RADIUS server(s(, and then acting on the response.
RADIUS servers are responsible for receiving user connection requests,
authenticating the user, and then returning all configuration information
necessary for the client to deliver service to the user.
In BreezeMAX systems, a RADIUS NAS is implemented in each Base Station.
Transactions between the client and RADIUS server are authenticated using
Password Authentication Protocol (PAP) through encryption based on RSA
Message Digest Algorithm MD5 and a Shared Secret, which is never sent over the
network.
The Access-Request is submitted to the RADIUS server via the network. If no
response is returned within a length of time, the request is re-sent a number of
times. Once the RADIUS server receives the request, it validates the sending
client. A request from a client for which the RADIUS server does not have a shared
