Strange Attractors and TCP/IP Sequence Number Analysis - One Year Later

Hello, Over a year ago, I published a paper that attempted to analyze the randomness of PRNGs used in TCP/IP stacks on several operating systems. The approach I've chosen resulted in detecting some non-trivial dependencies in several generators, and some amusing 3D pictures. The original RAZOR...
