Hi, This patch set adds SP800-90B compliance to the Jitter RNG. The SP800-90B patch is tested for more than half a year in user space with the Jitter RNG version 2.2.0. The full SP800-90B assessment of the Jitter RNG is provided at [1]. In addition, the DRBG implementation is updated to always be reseeded from the Jitter RNG. To ensure the DRBG is reseeded within an appropriate amount of time, the reseed threshold is lowered.
