White Paper
Designing a Hybrid Path to PQC Built for the Real World
SoftBank and SandboxAQ’s white paper outlines a hybrid path to post-quantum cryptography (PQC), combining classical encryption (e.g., RSA, ECC) with quantum-resistant algorithms to counter “store-now-decrypt-later” threats. Real-world tests across Wi-Fi, LTE, 5G, and VPNs showed structured lattice-based PQC (ML-KEM, ML-DSA) delivers strong security with minimal performance impact. Benefits include immediate quantum safety, smooth integration, and regulatory readiness. Best practices: inventory cryptographic assets, test PQC algorithms, build crypto-agility, and adopt hybrid encryption for gradual, secure transition to full quantum-safe systems.
