Optimization of optical random number generation and lexicographic postprocessing parameters based on the integral evaluation of NIST tests

Key Points

• The aim is to identify the best parameters for optical random number generation and postprocessing using an integral evaluation.
• Propose an integral indicator that combines multiple performance metrics.
• Analyze the arithmetic mean and median percentages of NIST test results.
• Evaluate the proportion of results that exceed a specified threshold.
• The proposed method integrates key metrics to determine optimal parameters.
• Findings suggest improved performance of optical random number generation under the new framework.
• Successful outcomes align with standard NIST testing criteria.
