A new Request for Comments is now available in online RFC libraries. RFC 8471 Title: The Token Binding Protocol Version 1.0 Author: A. Popov, Ed., M. Nystroem, D. Balfanz, J. Hodges Status: Standards Track Stream: IETF Date: October 2018 Mailbox: andreipo@microsoft.com, mnystrom@microsoft.com, balfanz@google.com, Jeff.Hodges@KingsMountain.com Pages: 18 Characters: 39858 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-tokbind-protocol-19.txt URL: https://www.rfc-editor.org/info/rfc8471 DOI: 10.17487/RFC8471 This document specifies version 1.0 of the Token Binding protocol. The Token Binding protocol allows client/server applications to create long-lived, uniquely identifiable TLS bindings spanning multiple TLS sessions and connections. Applications are then enabled to cryptographically bind security tokens to the TLS layer, preventing token export and replay attacks. To protect privacy, the Token Binding identifiers are only conveyed over TLS and can be reset by the user at any time. This document is a product of the Token Binding Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
