Lattice-Based Cryptography for Internet-of-Things in Post-quantum Computing

In Post-Quantum Cryptography (PQC), the acceptance of scalable quantum computers has been encouraged as lattice-based cryptography is the driving force technique among numerous quantum–resistant cryptography ideas. Half of the ‘survivors’ are lattice-based in architecture and have been accepted and standardized from the PQC competition conducted by the National Institute of Standards and Technology (NIST). This paper assesses the practicality of these schemes being deployed. This paper critically examines and classifies fundamental concepts of Lattice-Based Cryptography (LBC) and its approaches. In aspects of various benchmarks of the Internet of Things’ critical performance, the review concludes with the recognition of some preferred LBC schemes.
