Diffie Hellman isn't a public key encryption scheme, it's a key exchange protocol using public key cryptography. These algos are an alternative to RSA or elliptic curve. Why they have separate encryption and signing algorithms I can only guess. They list one of the schemes as a key establishment protocol a.k.a. key exchange, which leads you to believe its optimized for a very small amount of data, perhaps less than a few hundred bytes for establishing a symmetric key which is immune to quantum
Yeah my question was whether the CRYSTALS-KYBER key exchange is based upon a similar "secret paint mixing" technique as DH or whether my knowledge of how existing crypto systems work is totally useless in this realm
Are these algorithms based on DH at all or are they totally different?
Diffie-Helman? Different.
Thanks
