Abstract
A hybrid random number generator (HRNG) including an output, a combinational logic, a TRNG, and a PRNG. The HRNG is configurable to operate in a first and a second mode, wherein in the first mode the PRNG is serially connected between the TRNG and the output and the TRNG intermittently influences the PRNG, and in the second mode the TRNG and the PRNG are connected to the output via the combinational logic.
