PQE Encryption

Quantum computers capable of breaking RSA and elliptic curve cryptography (ECC) are projected to arrive within the next decade, and nation-state programs are accelerating that timeline. Data encrypted today with classical algorithms is vulnerable to a 'harvest now, decrypt later' attack strategy, where adversaries collect encrypted traffic now with the intention of decrypting it once quantum capability is available. This is not a theoretical concern — intelligence agencies have confirmed that state actors are already stockpiling encrypted data for future decryption. For organizations handling classified information, financial data, healthcare records, or long-lived intellectual property, the window to act is now. PQE addresses this threat by deploying quantum-resistant algorithms today, ensuring that data encrypted now remains secure regardless of advances in quantum computing.

PQE uses ML-KEM (Module-Lattice Key Encapsulation Mechanism), the primary post-quantum key encapsulation standard published by NIST in 2024. The ML-KEM-768 parameter set provides 256-bit equivalent security with efficient key generation, encapsulation, and decapsulation operations suitable for high-throughput enterprise environments. During the transition period from classical to post-quantum cryptography, PQE supports a hybrid mode that pairs ML-KEM with traditional algorithms like X25519, ensuring backward compatibility while adding quantum resistance. The hybrid approach means that even if an unforeseen vulnerability is discovered in the post-quantum algorithm, the classical layer still provides protection. Encryption is applied transparently at the data layer, requiring no changes to application code or user workflows.

PQE provides centralized key management with distributed enforcement, allowing security teams to define key policies from a single control plane while keys are enforced at every node in the infrastructure. Hardware security module (HSM) integration ensures that master keys never exist in plaintext outside tamper-resistant hardware boundaries. Automated key rotation executes zero-downtime transitions on configurable schedules, re-encrypting data in the background without disrupting active workloads. All cryptographic modules are FIPS 140-3 validated, meeting the highest federal standards for cryptographic implementation. The key management system supports multi-tenant isolation, enabling managed service providers and large enterprises to maintain cryptographic separation between organizational units.
