Abstract
Unpredictable random numbers are used to provide the parameter values and seeds for a parameterized random number generator, thereby providing forensic reproducibility of a simulation. The values generated unpredictably to provide the parameters and seeds for the random number generator are stored so that the same random numbers can be utilized for a subsequent computation in the simulation.
Claims20
A computer implemented method for generating random numbers for configuring a forensically reproducible simulation, the method comprising:
- maintaining, by a computer processing system, an unpredictable random number generator and a parameterized random number generator;
- generating, by the unpredictable random number generator of the computer processing system, a plurality of unpredictable random numbers, wherein each of the plurality of unpredictable random numbers comprises a plurality of bits;
- outputting, by the unpredictable random number generator of the computer processing system, the plurality of unpredictable random numbers to a memory of the computer processing system;
- and
- when a reproducible random number is required for a forensically reproducible simulation executing on the computer processing system:
- selecting one of the plurality of unpredictable random numbers stored in the memory of the computer processing system;
- initializing the parameterized random number generator of the computer processing system using the selected one of the plurality of unpredictable random numbers;
