Abstract
A random number generator resistant to side-channel attacks. The random number generator includes an entropy unit generating random pulses, a random frequency clock generator generating random frequencies by receiving random pulses output from the entropy unit, and an MCU externally masking a specific operation or a specific instruction based on a random frequency received from the random frequency clock generator.
