A new Request for Comments is now available in online RFC libraries. RFC 7619 Title: The NULL Authentication Method in the Internet Key Exchange Protocol Version 2 (IKEv2) Author: V. Smyslov, P. Wouters Status: Standards Track Stream: IETF Date: August 2015 Mailbox: svan@elvis.ru, pwouters@redhat.com Pages: 12 Characters: 24593 Updates: RFC 4301 I-D Tag: draft-ietf-ipsecme-ikev2-null-auth-07.txt URL: https://www.rfc-editor.org/info/rfc7619 DOI: http://dx.doi.org/10.17487/RFC7619 This document specifies the NULL Authentication method and the ID_NULL Identification Payload ID Type for Internet Key Exchange Protocol version 2 (IKEv2). This allows two IKE peers to establish single-side authenticated or mutual unauthenticated IKE sessions for those use cases where a peer is unwilling or unable to authenticate or identify itself. This ensures IKEv2 can be used for Opportunistic Security (also known as Opportunistic Encryption) to defend against Pervasive Monitoring attacks without the need to sacrifice anonymity. This document is a product of the IP Security Maintenance and Extensions 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.
