Abstract: The paper provides an overview and analysis of the current state, problems, and prospects of post-quantum key encapsulation mechanisms. The essential cryptographic building blocks for implementing secure communication protocols are key-encapsulation mechanisms. KEMs enable two parties to securely establish a shared secret key over an insecure channel. This shared key can then be used for symmetric encryption of messages, ensuring confidentiality and integrity of the exchanged data. The National Institute of Standards and Technology (NIST) is actively working on standardizing post-quantum cryptography including KEMs. After the third round of the NIST PQC Standardization Process, NIST has identified the CRYSTALS-KYBER KEM algorithm for standardization. The four algorithms selected for a fourth round are BIKE, Classic McEliece, HQC, and SIKE. In this paper, we explore all these algorithms.
