Pulse Analysis

The looming arrival of quantum computers forces a rethink of cryptographic safeguards across the sprawling Internet of Things. Traditional benchmarks focus on isolated metrics—often measuring latency or key size in isolation—leaving system architects blind to the compound impact on battery life, processing headroom, and wireless reliability. By treating these variables as interdependent, a holistic assessment becomes essential for devices that operate on limited power budgets and intermittent connectivity.

QERS addresses this gap with a multi‑criteria decision framework that normalizes six core performance indicators and fuses them into a single resilience score. Its three scoring modes let engineers toggle between rapid high‑level comparisons (Basic), context‑specific weighting (Tuned), and a comprehensive blend of performance and security sub‑scores (Fusion). The methodology was validated on an ESP32‑C6 platform, testing Kyber, Dilithium, Falcon, SPHINCS+, and NTRU under varied wireless conditions. The results expose hidden trade‑offs—for instance, an algorithm with modest latency may impose disproportionate energy costs—enabling precise algorithm selection aligned with deployment priorities.

For industry, QERS offers a reproducible, extensible tool that can be integrated into product development pipelines and standards‑setting processes. Its hardware‑centric approach ensures relevance beyond simulation, while the modular design invites future metrics such as temperature effects or packet‑loss variance. As regulatory bodies and OEMs chart migration paths toward quantum‑resistant IoT, frameworks like QERS will be pivotal in balancing security imperatives with the practical limits of edge devices.
