Abstract

A truly random number generator and a truly random number generation method for conversion of a bridge voltage at random intervals in an MCU, comprising an MCU, a bridge module, and an amplifier, the MCU comprising an application module, a random number generation module, and an ADC module. A power supply VCC is separately connected to the bridge module and the amplifier by means of a switch SW, an output terminal of the bridge module is connected to the amplifier, an output terminal of the amplifier is connected to the ADC module, the ADC module is connected to the random number generator, and the random number generator is connected to the application module. An output of a bridge passes through an amplifier, and then the output thereof is converted by an ADC. The bit length of a truly random number can be controlled by means of an application module, and the working mode thereof is flexible, able to be used in various use scenarios for communications systems, and in encryption algorithms requiring various random number bit lengths.
