The security strength of many systems and applications is dependent on the quality of random number generators. Many cryptographic operations require a source of random numbers, such as the creation of cipher keys and initial values for counters and protocol parameters.
The DesignWare® True Random Number Generator (TRNG) Core for NIST SP 800-90c is compliant with NIST SPA800-90A/B/c and BSI AIS 20/31 specifications. It generates random numbers that are statistically equivalent to a uniformly distributed data stream. The core includes a NIST SP800-90B approved conditioning circuit with a compliant noise source and NIST SP 800-90A approved Deterministic Random Bit Generator (DRBG) using the terminology preferred by the National Institute of Standards and Technology (NIST). The core generates random numbers that are intended to be statistically equivalent to a uniformly distributed data stream. The noise source does not depend on process-specific circuitry and is therefore very portable across different ASIC and FPGA fabrication technologies. When implemented in silicon, the DesignWare TRNG can meet or exceed the highest commercial and US government SBU standards.
