LONDON, 22 JAN — Quantum storm looms. Tests show lattice-based shields (Kyber, Dilithium) hold best on weak devices. McEliece too bulky, SPHINCS+ too costly in bandwidth. For wearables & hubs, the defense must be lean. Urgent deployment guidance issued. #PQC #QuantumThreat
LONDON, 22 JANUARY — Quantum dawn breaks; the old ciphers—RSA, ECC—crack under simulated assault. Field trials of post-quantum armor complete. On Apple’s M4 and x86 fortresses, all candidates withstand. But in the trenches of Raspberry Pi 4, only ML-KEM and ML-DSA endure, their lattice walls holding with modest overhead. Classic McEliece, though impregnable, demands supply trains of storage—keys stretch into megabytes, unfit for wrist-worn sentinels. SPHINCS+ stands fast, but each signature leaves a trail too wide for narrowband channels. The verdict: for smart hubs, mobiles, wearables, the future lies in balanced defenses—efficient, compact, deployable now. Delay risks the entire consumer front. Manufacturers must arm accordingly—before the quantum offensive begins in earnest.
