A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Security Protocol Working Group of the IETF.

	Title		: Security Architecture for the Internet Protocol
	Author(s)	: S. Kent, K. Seo
	Filename	: draft-ietf-ipsec-rfc2401bis-02.txt
	Pages		: 78

This memo specifies the base architecture for IPsec compliant systems.  The goal of the architecture is to provide various security services for traffic at the IP layer, in both the IPv4 and IPv6 environments.  This document describes the goals of such systems, their components and how they fit together with each other and into the IP environment.  It also describes the security services offered by the IPsec protocols, and how these services can be employed in the IP environment.  This document does not address all aspects of IPsec architecture.  Subsequent documents will address additional architectural details of a more advanced nature, e.g., use of IPsec in NAT environments and more complete support for IP multicast.  The following fundamental components of the IPsec security architecture are discussed in terms of their underlying, required functionality. Additional RFCs (see Section 1.3 for pointers to other documents) define the protocols in (a), (c), and (d).

In the body type:

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
