Prime Random Number Generator
Description
Reference design
The BA431 True Random Generator produces random bit data which is concatenated in a shift register. The flexible architecture allows to easily define the width of the generated random number (128-, 256-, 1024-, 2048-, 4096-bit).
Guaranteed average performances
The control logic implements an optimized Prime Random Number Generation (PRNG) algorithm that can guarantee the average performances. Depending on the requirements, the architecture can be adapted to match the specifications. Thanks to the extreme performances of the BA414E crypto engine, very fast PRNG rate is achieved with small silicon usage.
Randomization of random (optional)
Some random number generation standard (such as NIST) requires randomization of the generated random number. With the flexible BA413 hash crypto core, this reference design follows the NIST specification SP800-90 §10.1.1 with Hash DRBG based on SHA-256.
Sieving (optional)
The sieving feature allows to further increase the performances of the architecture. The sieving module quickly tests the random numbers and discards those that are obviously not prime.
Rabin-Miller
The Rabin-Miller algorithm is the most common and reliable primality test for hardware implementations.
The flexible BA414E crypto engine offers an optimal implementation of the Rabin-Miller algorithm. Thanks to its unique architecture, it provides ideal flexibility and unrivalled performances.
