Now for the question you may have: Can a re-seed hurt security? earl griffin attorney childress texasWebAug 11, 2024 · In fact, the CTR DRBG is used in Intel chips for the RDRAND and RDSEED instructions. A hardware RNG is used to generate a set of bits, which are then tested and debiased, and those bits are then used to seed a CTR DRBG instance in hardware. But either way, the two terms are mostly equivalent. Share Improve this answer Follow css height scroll
