Currently, the security of these devices relies on classical cryptographic primitives such as RSA and Elliptic Curve Cryptography (ECC). However, the imminent advent of large-scale fault-tolerant quantum computers threatens to render these standards obsolete via Shor's Algorithm. To address this existential threat, the National Institute of Standards and Technology (NIST) has standardized ML-KEM (Kyber) as the primary Post-Quantum Cryptography (PQC) algorithm. While Kyber is efficient on server-grade hardware, its implementation on low-power, battery-operated IoT devices remains a significant challenge due to limited processing power and memory. This paper investigates the feasibility of Kyber-512 (ML-KEM-512), a lightweight variant of the standard, specifically tailored for constrained environments. Utilizing a high-fidelity ARM64 emulation environment (QEMU) to simulate modern IoT architecture, we conducted extensive benchmarking of cryptographic operations. Our experimental results demonstrate an encapsulation latency of approximately 0.200 milliseconds and a decapsulation latency of 0.229 milliseconds. These findings confirm that lightweight PQC can be deployed on current IoT hardware with negligible performance overhead, ensuring robust protection against future quantum threats without compromising device longevity.
