Post-Quantum Cryptography (PQC)
“Post-Quantum” refers to securing systems so they cannot be broken by a quantum computer. If your Planck-scale system connects to any network, its software stack requires immediate quantum-resistant architecture: [1]
Hybrid Security Layering: During deployment, the system must run classical encryption (like AES-256) and post-quantum algorithms in parallel to guarantee backward compatibility and security. [, 2, 3, 4, 5]
Lattice-Based Math Algorithms: The system must abandon traditional RSA and ECC encryption. It must implement standardized, NIST-approved algorithms like ML-KEM (for key encapsulation) and ML-DSA (for digital signatures), which rely on the high-dimensional geometric complexity of lattices. [1, 2, 3, 4]
Crypto-Agility: The software architecture must be highly flexible. This allows engineers to swap out cryptographic keys, protocols, and algorithms seamlessly without needing to redesign the underlying hardware. [1, 2]
