Injecting cpu time jitter to improve entropy quality for random number generator

A method of injecting central processing unit (CPU) time jitter to improve entropy quality of a random number generator, comprising:

• receiving, at an input/output interface module of the random number generator, a request to generate a random number, wherein the requested random number comprises a plurality of random bits;
• and
• initiating a random bit generating loop to generate each of the plurality of random bits of the random number to be generated, wherein the random bit generating loop comprises:
• incorporating a CPU time as a randomness factor in generating the random number to improve entropy quality of the random number generator;
• generating a candidate bit by using a clock time;
• and
• generating a random bit for the random number by using a von Neumann unbiasing analysis module, until every random bit of the random number is generated.

A computer program product operable on a central processing unit (CPU) of a computer comprising a non-transitory computer readable storage medium having computer executable instructions embodied therewith, wherein when executed by the CPU, the computer executable instructions cause the CPU to perform:

• receiving, at an input/output interface module of a random number generator, a request to generate a random number, wherein the requested random number comprises a plurality of random bits;
• and
• initiating a random bit generating loop to generate each of the plurality of random bits of the random number to be generated, wherein the random bit generating loop comprises:
• incorporating a CPU time as a randomness factor in generating random number to improve entropy quality of the random number generator;
• generating a candidate bit by using a clock time;
• and
• generating a random bit for the random number by using a von Neumann unbiasing analysis module, until every random bit of the random number is generated.
