Transport Layer Security (TLS) Encryption for RADIUS
Abstract
This document specifies a transport profile for RADIUS using
Transport Layer Security (TLS) over TCP as the transport protocol.
This enables dynamic trust relationships between RADIUS servers.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Engineering
Task Force (IETF). It represents the consensus of the IETF
community. It has received public review and has been approved for
publication by the Internet Engineering Steering Group (IESG). Not
all documents approved by the IESG are a candidate for any level of
Internet Standard; see Section 2 of RFC 5741.
