Hi.  I'm wondering if anybody is aware of any examples of neural networks
being used for any kind of cryptography-related purpose.  If anybody is,
I'd be very thankful for references or pointers.

As I'm not a regular reader of either of these groups, email is preferable.
I'll scan for posts, however.  I'm also glad to summarize upon request--
assuming there's something to summarize, of course.


Thanks.

At one of the Crypto conferences, I remember someone talking about someone
else who had requested time on a Cray computer to attempt to break DES
with a neural net.  I don't think the request was granted.

The problem with using neural nets is figuring out what to reward.  Each bit
is going to be correct 50% of the time, on the average.  How do you judge
"almost correct"?

It's an interesting question, one I'm sure the spooks have played with, but
I don't know of anyone in the non-military world getting anywhere.
