In the context of the NIST standardization process for identifying and analyzing Post-Quantum Cryptography (PQC) solutions, the first crucial outcome is the selection of the key encapsulation mechanism (KEM) CRYSTALS-Kyber.
Kyber is a public-key cryptographic scheme that allows two parties to derive a common secret with which to protect the exchange of information.
The major features, which allowed Kyber to be selected as the primary solution within KEM among the initial 45 NIST proposals, are to be found in its efficiency and guaranteed security in the face of the best-known classical and quantum attacks in the literature.
Within current cryptographic protocols, Kyber will replace cryptographic key exchange techniques based on problems vulnerable to quantum computing such as the widely used ECDH, Diffie Hellman key exchange built on elliptic curves.
