Take a look at how the regs are actually worded. This is 5A002 of
15 CFR 774, the Commerce Control List.
: List of Items Controlled
:
: Items:
:
: a. Designed or modified to use ``cryptography'' employing digital
: techniques to ensure ``information security'';
: b. Designed or modified to perform cryptanalytic functions;
: c. Designed or modified to use ``cryptography'' employing analog
: techniques to ensure ``information security'';
:
: ... a bunch more, not relevant ...
:
: Note: 5A002 does not control:
:
: ... skipping some, we come to ...
:
: g. Data authentication equipment that calculates a Message
: Authentication Code (MAC) or similar result to ensure no alteration of
: text has taken place, or to authenticate users, but does not allow for
: encryption of data, text or other media other than that needed for the
: authentication;
(g) is the exemption which Ron Rivest is trying to exploit. But once
you set up your MAC system so that it provides secrecy, you lose the
exemption.
