Abstract
A true random number generator is provided. The true random number generator includes an Exclusive-Or (XOR) circuit and multiple random entropy source circuits. One entropy source sampling process is performed at an output terminal of each of at least two inverters in each of the multiple random entropy source circuits, which is performed by a flip-flop corresponding to the inverter. Sampling results are inputted to an XOR unit in the random entropy source circuit and XOR processing is performed on the sampling results. XOR processing results outputted by the multiple of random entropy source circuits are inputted to the XOR circuit, and the XOR processing is performed on the XOR processing results to obtain a random number sequence.
