This paper investigates the feasibility of a quantum-secure Key Encapsulation Mechanism (KEM) in hardware constrained Smart Meter (SM) equipment. In this sense. the Cryptographic Suite for Algebraic Lattices (CRYSTALS)-Kyber scheme. the new standard for post-quantum Public-Key Encryption (PKE) systems chosen by the post-quantum cryptography (PQC) standardization process. https://www.roneverhart.com/
