Evaluating Post-Quantum Cryptography on Embedded Systems: A Performance Analysis

Abstract

The National Institute of Standards and Technology (NIST) has finalized the selection of post-quantum cryptographic (PQC) algorithms for use in the era of quantum computing. Despite their integration into TLS protocol for key establishment and signature generation, there is limited study on profiling these newly standardized algorithms in resource-constrained communication systems. In this work, we integrate PQC into both TLS servers and clients built upon embedded systems. Additionally, we compare the performance overhead of PQC pairs to currently used non-PQC schemes.
