Surprisingly, I was able to make it reasonably practical. You can find well-documented reference code with test cases at - http://gawth.com/bram/CheapSignaturesBeta.py I would much appreciate it if anyone would analyze the code - I'm pretty sure it's secure, since it's use of hashes falls within my area of expertise, but don't really feel confident until other people have looked at it as well. I suspect at least some of the ideas are original, although I haven't looked at the literature much - I'm particularly proud of the 165 choose 82 trick.
