Radius/UDP. How legacy protocols need to keep up with modern cryptography

There is a typo in the document. It should read "RADIUS over TLS or DTLS" not "RADIUS over TLS or DLTS" (above the second image). The "DLTS" is wrong.

Huh. Most people who care have already moved to Diameter (this is not a joke, that’s the actual name of the new protocol).
