A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the TCP Maintenance and Minor Extensions Working Group of the IETF. Title : The TCP Authentication Option Author(s) : J. Touch, et al. Filename : draft-ietf-tcpm-tcp-auth-opt-02.txt Pages : 36 Date : 2008-11-03 This document specifies the TCP Authentication Option (TCP-AO), which obsoletes the TCP MD5 Signature option of RFC-2385 (TCP MD5). TCP-AO specifies the use of stronger Message Authentication Codes (MACs), protects against replays even for long-lived TCP connections, and provides more details on the association of security with TCP connections than TCP MD5. TCP-AO is compatible with either static keying or an external, out-of-band key management mechanism; in either case, TCP-AO also protects connections when using the same key across repeated instances of a connection. The result is intended to support current infrastructure uses of TCP MD5, such as to protect long-lived connections (as used, e.g., in BGP and LDP), and to support a larger set of MACs with minimal other system and operational changes. TCP-AO uses its own option identifier, even though used mutually exclusive of TCP MD5 on a given TCP connection. TCP-AO supports IPv6, and is fully compatible with the requirements for the replacement of TCP MD5.
