WebAug 3, 2024 · For instance, the DRBG's specified by NIST all provide a reseeding operation, which is missing from AES-CTR. Although they do provide a counter based operation as well, AES-CTR clearly doesn't qualify.

Random Number Generator based on AES CTR
Several CSPRNGs have been standardized. For example, • FIPS 186-4 • NIST SP 800-90A: This withdrawn standard has four PRNGs. Two of them are uncontroversial and proven: CSPRNGs named Hash_DRBG and HMAC_DRBG. There are three functions exposed on the Kyberclass which are intendedfor use: 1. Kyber.keygen(): generate a keypair (pk, sk) 2. Kyber.enc(pk): generate a challenge and a shared key (c, K) 3. Kyber.dec(sk, c): generate the shared key K To use Kyber() it must be initialised with a dictionary of theprotocol parameters. An … See more Under no circumstances should this be used for a cryptographic application. I have written kyber-pyas a way to learn about the way Kyber works, and totry and create a clean, well commented implementation … See more A great resource for learning Kyber is available atApproachable Cryptography.
