Title:
METHOD FOR GENERATING RANDOM NUMBER, CHIP, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/113844
Kind Code:
A1
Abstract:
A method for generating a random number, a chip, and an electronic device. The method comprises: obtaining an entropy source, the entropy source comprising a physical random number and information of a chip (S210); generating a random number seed according to the entropy source (S220); and generating a random number according to the random number seed and an encryption algorithm of the chip (S230). The method can improve the quality of a random number generated by a chip.
