A SoC Implementation of a PQC Scheme for Smart Meter

This paper focuses on the implementation a quantum-secure lattice-based cryptography as a key encapsulation mechanism for a smart meter device, which has hardware resource constraint. In this regard, the post-quantum cryptography scheme called FrodoKEM, a candidate to the NIST post-quantum standardization process, is implemented using a system-on-a-chip (SoC) device. Numerical results show that the processing time to run the FrodoKEM scheme implemented in a SoC device reduces in comparison to the benchmark implementation. At the end, we conclude that this SoC-based implementation of the FrodoKEM scheme may fits the hardware constraints related to smart meter devices.
