A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Integer Counter Mode
Author(s) : D. McGrew
Filename : draft-irtf-cfrg-icm-00.txt
Pages : 8
Date : 2002-10-30
This document specifies Integer Counter Mode (ICM), a mode of
operation of a block cipher which defines an indexed keystream
generator (which generates a keystream segment given an index).
This mode is efficient, parallelizable, and has been proven secure
given realistic assumptions about the block cipher. Test vectors
are provided for AES.
Counter Mode admits many variations. The variant specified in
this document is secure and flexible, yet it enables a single
implementation of a keystream generator to suffice in different
application domains.

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
Internet-Draft.
