  • Random number generating circuit and process
    Patent number: 6581078
    Abstract: A random number generating circuit and process are provided with a physical noise source which produces digital signals which are combined with signals produced by a pseudo-random number generator. The combined signals are sent to the input of the pseudo-random number generator. The resulting digital signals are thus unpredictable while exhibiting the intended statistical characteristics. The random number generating circuit is suitable for cryptography.
