  • True random number generation device and generation method thereof
    Patent number: 10776079
    Abstract: A true random number generation device and a true random number generation method are provided. The true random number generation device includes a selection signal providing circuit and a linear feedback shift register. The selection signal providing circuit is configured to provide a true random selection signal. The linear feedback shift register includes true random number generators of a plurality of stages. The Nth stage true random number generator is configured to receive a clock signal and a N?1th bit true random number. The Nth stage true random number generator generates a plurality of Nth stage output logic values according to the clock signal and the N?1th bit true random number, and selects one of the plurality of Nth stage output logic values to be a Nth bit true random number according to the true random selection signal.
