Mennyire véletlen az a véletlen szám

Over a year ago, I published a whitepaper titled "Strange Attractors and TCP/IP Sequence Number Analysis" - an attempt to evaluate TCP/IP sequence number generators in several mainstream operating systems by mapping the dynamics of the generated sequence numbers into a three-dimensional phase space. We demonstrated how this approach can be used to find many non-trivial correlations, and discussed why the results can be directly used to perform actual ISN prediction.
