These extensions permit the negotiation of an application protocol variant of RADIUS called "RADIUS/1.1". No changes are made to RADIUS/UDP or RADIUS/TCP. The extensions allow the negotiation of a transport profile where the RADIUS shared secret is no longer used, and all MD5-based packet authentication and attribute obfuscation methods are removed. This document updates RFCs 2865, 2866, 5176, 6613, 6614, and 7360.}, }
