Post-Processing Logic

Post-Processing Logic is a computational module within a Random Number Generator (RNG) that applies mathematical transformations to raw pseudorandom sequences. Its primary function is to improve statistical properties such as uniformity, independence, or distribution shape, ensuring the output meets application-specific quality standards. This component is essential in systems where the raw output from a core generator does not directly satisfy the stringent requirements of downstream applications like simulation, cryptography, or gaming.

The module receives raw pseudorandom numbers from a core generator and applies deterministic algorithms, including whitening, distribution shaping, and bias correction. These algorithms refine the sequence to enhance its statistical characteristics, making it suitable for target applications. The output bit rate ranges from 1 to 100 Mbps, which determines throughput for downstream encryption. Statistical uniformity is verified with a minimum p-value of 0.99 according to NIST SP 800-22, ensuring the output passes randomness tests. Processing latency is kept at or below 10 ms, which is critical for real-time applications.

Electrical and environmental specifications are defined for integration into electronic systems. The supply voltage is 3.3 V DC with a tolerance of ±5%, and power consumption does not exceed 0.5 W, affecting thermal design in compact devices. The operating temperature range is -40 to 85 °C, with storage from -55 to 125 °C, per IEC 60068-2-1 and IEC 60068-2-2, respectively. Relative humidity must be between 5% and 95% non-condensing, as condensation may cause shorts, per IEC 60068-2-78. Ingress protection is rated IP40 to IP65, suitable for dusty or wet environments, per IEC 60529.

The component uses AES-256 as the cryptographic post-processing algorithm, per FIPS 197, for security applications. It interfaces with host controllers via SPI or UART. The package type is QFN-32, per JEDEC MO-220, and the weight is 2 grams or less, affecting handling and mounting. The material on file is semiconductor silicon.

All listed values are directory reference ranges and must be confirmed with the legal manufacturer or supplier for the specific model and application. Standards are procurement references and do not imply certification or compliance of any product or supplier.

The Post-Processing Logic receives raw pseudorandom numbers from a core generator. It applies deterministic algorithms such as whitening, distribution shaping, and bias correction to refine the sequence. These algorithms improve statistical properties like uniformity and independence. The refined numbers are then output with enhanced characteristics suitable for target applications. The module operates within specified electrical and environmental limits, including supply voltage, temperature, and humidity, to ensure reliable performance.
