Abstract
A device for true random number generation is disclosed. The device comprises an antenna and an analog processing unit for analog processing of a signal received from the antenna. An analog to digital (AD) converter is used for converting an analog signal generated by the analog processing unit into a digital signal. An isolation means is applied for temporarily isolating the antenna from the analog processing unit and the AD converter to generate a noise signal. A sampling means is used for sampling output values generated by the AD converter when the antenna is isolated from the analog processing unit and the AD converter. A digital processing unit is used for processing the sampled output values generated by the AD converter. The digital processing unit is configured to generate a random number based on one or more of the output values generated by the AD converter.
