Non-physical true random number generator (NPTRNG),[1] also known as non-physical nondeterministic random bit generator is a true random number generator that does not have access to a dedicated hardware entropy source.[2] NPTRNG uses a non-physical noise source that obtains entropy from system data, like outputs of application programming interface functions, residual information in the random access memory, system time or human input (e.g., mouse movements and keystrokes).[3][1] A typical NPTRNG is implemented as software running on a computer.[1] The NPTRNGs are frequently found in the kernels of the popular operating systems[4] that are expected to run on any generic CPU.
