Title : Forward Secrecy Extensions for OpenPGP
Author(s) : I. Brown, A. Back, B. Laurie
Filename : draft-brown-pgp-pfs-00.txt

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.

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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
