The RADIUS Extensions (RADEXT) Working Group is chartered to carry out specific maintenance tasks for the RADIUS protocol as described below. To ensure backward compatibility with existing RADIUS implementations, all documents produced must specify means of interoperation with legacy RADIUS and, if possible, be backward compatible with existing RADIUS RFCs, including RFCs 2865-2869, 3162, 3575, 3579, 3580, 4668-4673, 4675, 5080, 5090, 5176, 5997, 6158, 6613, 6614, 6929, 7360, 7585, 8044, and 8559. The WG may revisit the status of existing RADIUS RFCs, possibly changing document track categories with minor changes in the documents as needed. Work Items The immediate goals of the RADEXT working group are to address the following issues: - Deprecate the use of insecure transports outside of secure networks. This work updates RFC 6421 where possible. - Bring RFC 6614 (RADIUS/TLS), and RFC 7360 (RADIUS/DTLS) to Standards track. - Define best practices for RADIUS roaming, and roaming consortia based on experience with RADIUS/TLS. - Improve operations for multi-hop RADIUS networks: e.g. loop detection and prevention, a multi-hop Status-Server equivalent with ability to Trace the proxy steps a RADIUS message will follow. - Extend the 8-bit RADIUS ID space to allow more than 256 "in flight" packets across one connection. - Allow for CoA / Disconnect packets to be sent in "reverse" down a RADIUS/TLS or RADIUS/DTLS connection. This functionality assists with transit of NATs. - Defining a secure variant of RADIUS which can be used in a FIPS-140 compliant environment. There is an external timeline that affects this work: completion by 2024 would enable WG outputs to be included in the planned WiFi 8 release. The WG will aim to meet that deadline. Adopting work items not described above will require a re-charter.
