This paper discusses the implications of quantum computing on modern cryptography, focusing on the Internet of Things (IoT). It highlights the potential threat posed by quantum computers to current public-key cryptosystems. The paper surveys existing literature on the performance of Post-Quantum Cryptography (PQC) in resource-constrained devices to understand the severity of this issue. It reviews recent proposals to optimize PQC algorithms for such devices. The study suggests that while PQC may be feasible for lightweight IoT devices, optimization proposals lack standardization. It recommends future research to ensure an efficient and safe transition to the post-quantum era for IoT.
