Ctr_drbg with derivation function
WebAug 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 WebFeb 12, 2024 · The benefit of re-seeding your DRBG should be clear: If the state of your DRBG gets compromised at any point, an attacker can re-compute all the outputs of the DRBG following up until the last reseed which limits the damage in case of an successful attack. Now for the question you may have: Can a re-seed hurt security?
