Abstract:

Post-quantum cryptography faces two challenges in resource-constrained Subscriber Identity Module (SIM): insufficient computing power/storage for high-complexity operations, and possible key leakage caused by side-channel and fault-injection attacks. This paper proposes a lightweight security architecture, designing an anti-side-channel accelerator with dynamic masking and constant-time number theoretic transform modules, plus a dual-protection mechanism of redundant computing and optical sensor shielding. Secure chip simulations show that the countermeasure can resist first-order side channel analysis and resist against fault injection attack, meeting global system for mobile communications association standards and enabling 5G/6G quantum-secure communication.

Key words: SIM, post-quantum cryptography, security defense, side channel analysis
