A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: Forward Secrecy Extensions for OpenPGP
	Author(s)	: I. Brown, A. Back, B. Laurie

The confidentiality of encrypted data depends on the secrecy of the
key needed to decrypt it. If one key is able to decrypt large
quantities of data, its compromise will be disastrous. This memo
describes three methods for limiting this vulnerability for OpenPGP
messages: reducing the lifetime of confidentiality keys; one-time
pads; and the additional use of lower-layer security services.

Internet-Drafts can also be obtained by e-mail.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-brown-pgp-pfs-00.txt".
	
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.

implementation to automatically retrieve the ASCII version of the
