Abstract
A system and method of generating a one-way function and thereby producing a random-value stream. Steps include: providing a plurality of memory cells addressed according to a domain value wherein any given domain value maps to all possible range values; generating a random domain value associated with one of the memory cells; reading a data value associated with the generated random domain value; generating dynamically enhanced data by providing an additional quantity of data; removing suspected non-random portions thereby creating source data; validating the source data according to a minimum randomness requirement, thereby creating a validated source data; and integrating the validated source data with the memory cell locations using a random edit process that is a masking, a displacement-in-time, a chaos engine, an XOR, an overwrite, an expand, a remove, a control plane, or an address plane module. The expand module inserts a noise chunk.
