	Title		: IPSec Replay Attack Protection in Multisender Environment

The IPsec Architecture [RFC2401] and IPsec transform RFCs [RFC2402, RFC2406] define certain mechanisms for protecting IP traffic. One of the mechanisms defined is replay attack protection. But this mechanism is not addressed in multisender environment where multiple senders are sending packets for same destination SA (This includes sharing of SA as well as multicast). This document reviews the issues in multisender environment and addresses solution for this by identifying the sending SA and having replay attack protection against each sending SA. The documents also summarizes the changes needed in AH, ESP, Key management protocols, which would enable IPSec to protect against replay attack protection in multisender environment for same destination SA.

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.
