I just got this message from NIST's Edward Roback. There seems to=
be a possibility that the AES contest could be endangered by
=
claims of intellectual property rights on competing algorithms.
U=
nfortunately some of the stronger candidates seem to be the less
e=
nlightened ones in this matter. It is a pity that NIST did not ask
=
for a clear statement to that effect before accepting the
candida=
tes. I suppose there is still time to apply some pressure
before a=
nnouncing the algorithms that will make it to the second
round.

Subject: draft Int. property slides
AES Submitters,
You m=
ay recall that last year we posed a question to you (on an infomral,
n=
on-binding basis) regarding intellectual property. There has been
int=
erest in providing a summary of what we found at the upcoming AES #2
c=
onference on March 22-23 during NIST's briefings to the conference. I
=
wanted to give each of you a chance to see our draft summary and
char=
acterization of your responses. Feel free to send me any comments you
=
may have.
Thanks!
Ed Roback, NIST
draft slide 1:
I=
ntellectual Property (IP)
Questions have been raised with NIST regar=
ding the possibility that
submitters may claim that their IP is infrin=
ged by the practice of another
candidate algorithm. So, in the spirit=
of trying to obtain a worldwide
royalty-free algorithm, NIST posed th=
e following question to the 15
submitters (for informal, non-binding r=
esponse):
Are you willing to waive any IP rights you may have on any=
party who makes,
uses, or sells implementations of the selected AES a=
lgorithm(s) (no matter
which algorithm is selected) ?
