Post-Quantum Handset eSIM

Technical Explanation

With quantum computers threatening classical RSA and ECC cryptosystems, 6G terminals integrate post-quantum cryptographic (PQC) accelerators directly into the eSIM/eSE (embedded Secure Element). The eSIM implements NIST-standardized lattice-based algorithms including ML-KEM (Kyber) for key encapsulation and ML-DSA (Dilithium) for digital signatures during 6G mutual authentication (6G-AKA), securing mobile banking, network subscription credentials, and device identity against store-now-decrypt-later attacks.

Key Functions

• Accelerates lattice-based polynomial multiplication in hardware
• Executes quantum-safe 6G-AKA authentication with the home core network
• Protects root subscriber keys (K) from quantum cryptanalysis
• Generates ephemeral session keys with forward secrecy
