[Full-disclosure] distributed cracking countermeasures

["Brian Eaton" <eaton.lists@xxxxxxxxx>]

I have a vague memory of somebody designing a cryptographic system or
puzzle that was supposed to be resistant to distributed cracking.  The
system was supposed to be intrinsically non-parallelizable.  You could
throw a bigger CPU at the problem, but more CPUs wouldn't help.

Does this ring any bells?

Regards,
Brian
