The urgent migration to post-quantum cryptography is complicated by a 3–10× increase in key sizes, which poses significant performance and storage constraints for resource-constrained IoT devices. Telecommunications operators must balance the immediate risk of "Harvest Now, Decrypt Later" attacks against the practical limitations of upgrading mission-critical networks without causing service disruption. A phased rollout strategy will be essential to manage the computational overhead while protecting subscriber data with lifecycles extending into the 2030s.
PQC Algorithms Need 3–10× Larger Keys for IoT Devices

Telcos preparing for post-quantum cryptography face challenges, as these algorithms require key sizes 3–10× larger than current standards.
Telecommunications companies face an immediate cryptographic threat as adversaries begin “Harvest Now, Decrypt Later” attacks, targeting sensitive subscriber data with lifecycles spanning five to ten years. While a large, general-purpose quantum computer remains under development, the potential for future decryption is driving a critical need to transition away from vulnerable public key cryptography. Industry expectations currently place a rough deadline of 2033 for PQC migration, coinciding with predictions for the arrival of workable quantum computers. However, implementing Post-Quantum Cryptography (PQC) presents significant hurdles; the algorithms themselves require key sizes…
