Circuit and method for controlling quality of random numbers |
摘要 |
<p>A random number quality control circuit capable of fast control of the level of random number quality is present. When a "0" output section and a "1" output section generate random numbers by individually receiving a random number signal, a random number quality monitor monitors an unbalance between the numbers of "0"s and "1"s. If a deviation from a desired ratio is found, a drive controller controls the reception characteristics of the "0" output section and "1" output section individually so that the deviation will be compensated for. The amount of information intercepted between a sender and a receiver can be reduced by maintaining the mark ratio of shared random numbers at 50%.</p> |
