Claim 11:
12. A method of generating an output random number, comprising:
during an initialization phase, generating an initial static random number sequence from an initial random number pool, generating an initial true random number sequence according to the initial static random number sequence and an initial dynamic random number sequence, and initiating a static random number pool according to the initial true random number sequence, wherein the initial random number pool is configured to contain truly random entropy bits; and
during an operation phase, outputting the output random number, generating a subsequent static random number sequence from the static random number pool, generating a subsequent true random number sequence according to the subsequent static random number sequence and a subsequent dynamic random number sequence, and updating the static random number pool according to the subsequent true random number sequence.
