Ganz so leicht ist es natürlich nicht

Ich habe nochmal nachgeschaut, wie POkerStars es beschreibt:
SHUFFLE
"Anyone who considers arithmetic methods of producing random digits is, of course, in a state of sin." - John von Neumann, 1951
We understand that a use of a fair and unpredictable shuffle algorithm is critical to our software. To ensure this and avoid major problems described in [2], we are using two independent sources of truly random data:
user input, including summary of mouse movements and events timing, collected from client software
true hardware random number generator developed by Intel [3], which uses thermal noise as an entropy source
Each of these sources itself generates enough entropy to ensure a fair and unpredictable shuffle.
