The AMD Versalâ„¢ device contains a true random number generator (TRNG). The TRNG enables applications to be compliant with AIS-20/31 and NIST-800-90A/B/C standards. To support these standards, the TRNG operates in three modes as shown in the following figure.

  1. Entropy source output
  2. Internal seed + DRNG output
  3. External seed + DRNG output

Features include:

  • Generates cryptographically secure random numbers
  • Generates data blocks with a 32-bit wide interface
  • Provides security strength of 256 bits
  • Ring oscillator and PLL random sources
