This comes up once in a while --- it appears an inappropriate approach, they say, since the solution space for the problem consists of exactly one spike, in the vast sea of all possible solutions ... there is no smooth contour over which to minimize the net's error function, and finding the one spike which is the correct result is no more efficient in such a case than any other exhaustive search. This argument would break down if there were detectable biases in the crypto algorithm that you could exploit. But then whether a nn would be the tool of choice in such a case may be uncertain.

Hi Folkd
Just sat through a lecture on an itroduction to Neural Nets.
Thought. Does anybody know of any tools that use Neural Nets to break ciphers?
Cheers
