The Internet of Things has a quantum problem nobody talks about enough. Billions of devices - smart sensors, industrial controllers, medical devices, connected cars - will operate for 10-30 years. They were built using today's cryptography: RSA signatures for firmware updates, ECC keys for authentication, weak random number generators. These devices can't easily be updated - some have firmware burned into ROM, others are embedded in concrete or deployed in remote locations. Yet in 10 years, quantum computers will break their security. The challenge combines resource constraints (IoT devices have limited CPU, memory, power) with longevity (they stay deployed for decades) and scale (updating billions of devices). The solution requires: lightweight post-quantum algorithms like FALCON that fit in constrained devices, quantum random number generation like Tropos for truly unpredictable keys, crypto-agility in firmware allowing algorithm updates, and planning for quantum security at design time. QNu Labs addresses this through Qosmos, our entropy-as-a-service that provides quantum randomness to IoT fleets.
75 billion IoT devices expected by 2025. Research shows 57% lack basic security. Their long lifecycles mean devices deployed in 2024 must resist attacks in 2034 when quantum computers likely exist. Firmware signatures using ECDSA become forgeable, authentication protocols using ECC become hackable, and weak RNGs become predictable. This threatens critical infrastructure, industrial systems, and medical devices.
A compromised IoT device isn't just a security issue - it's a safety issue. Industrial controllers running factories, medical pumps delivering medication, automotive systems controlling brakes. Quantum-safe IoT security prevents these systems from becoming vulnerable as they age. It also enables secure smart cities, where sensors stay deployed for decades but must remain trustworthy.
