Abstract (en)

[origin: WO2023274872A1] The present invention relates to a method for generating a random value (100) by means of a microcontroller (104), wherein an analog temperature signal (110) of an internal temperature sensor (106) of the microcontroller (104) is digitalized by means of an internal analog-to-digital converter (108) of the microcontroller (104) to form a binary temperature value (112), and wherein the random value (100) is derived from the binary temperature value (112).
