This document specifies a TCP Authentication Option (TCP-AO) which is 
intended to replace the TCP MD5 Signature option of RFC-2385 (TCP 
MD5). TCP-AO specifies the use of stronger Message Authentication 
Codes (MACs) and provides more details on the association of security 
associations with TCP connections. TCP-AO assumes an external, out-
of-band mechanism (manual or via a separate protocol) for session key 
establishment, parameter negotiation, and rekeying, replicating the 

 separation of key management and key use as in the IPsec suite. The 
result is intended to be a simple modification to support current 
infrastructure uses of TCP MD5, such as to protect BGP and LDP, and 
to support a larger set of MACs with minimal other system and 
operational changes. TCP-AO uses a new option identifier, even though 
it is intended to be mutually exclusive with TCP MD5 on a given TCP 
connection. It supports IPv6, and is fully compatible with 
requirements under development for an update to TCP MD5.
