Title : DTLS as a Transport Layer for RADIUS
Author(s) : A. DeKok
Filename : draft-ietf-radext-dtls-01.txt
Pages : 18

The RADIUS protocol [RFC2865] has limited support for authentication
and encryption of RADIUS packets. The protocol transports data "in
the clear", although some parts of the packets can have "hidden"
content. Packets may be replayed verbatim by an attacker, and
client-server authentication is based on fixed shared secrets. This
document specifies how the Datagram Transport Layer Security (DTLS)
protocol may be used as a fix for these problems. It also describes
how implementations of this proposal can co-exist with current RADIUS
