Post-Quantum Cryptography | RaaS Solutions

⚠️ The Quantum Threat

Quantum computers pose an existential threat to current public-key cryptography. Algorithms like RSA, ECDSA, and even Ed25519 rely on mathematical problems (factoring, discrete logarithm) that quantum computers can solve efficiently using Shor's algorithm.

"Harvest now, decrypt later" attacks are already happening: adversaries collect encrypted data today to decrypt it once quantum computers become powerful enough.

The time to act is now. Organizations must transition to quantum-resistant cryptography before it's too late.

🛡️ Why Post-Quantum Cryptography Matters

Cryptographic keys are the foundation of digital security. They protect:

Digital signatures — Verify authenticity and integrity of documents, software, and communications
Certificate authorities — Root of trust for the entire internet PKI infrastructure
Encrypted communications — Protect sensitive data in transit (TLS, VPNs, messaging)
Financial transactions — Secure blockchain, cryptocurrency, and banking operations
Government secrets — Classified information with decades-long confidentiality requirements
Intellectual property — Trade secrets and proprietary technology

Without quantum-resistant cryptography, all of these security guarantees collapse when large-scale quantum computers emerge.

📜 NIST Post-Quantum Standards

After an 8-year evaluation process, NIST has standardized post-quantum cryptographic algorithms designed to resist attacks from both classical and quantum computers:

2016 — Competition Launch

NIST begins post-quantum cryptography standardization project with 82 initial submissions.

2020 — Finalists Announced

Seven finalists selected after three rounds of evaluation based on security, performance, and implementation.

2024 — FIPS Standards Released

NIST publishes FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) as official standards.

🎯 FIPS 204: ML-DSA (Module-Lattice Digital Signature Algorithm)

ML-DSA is NIST's primary recommendation for post-quantum digital signatures. It's based on the hardness of lattice problems, which remain secure against quantum attacks.

Security Foundation

Based on Module Learning With Errors (M-LWE) problem over polynomial rings

Standardization

NIST FIPS 204 (August 2024), previously known as CRYSTALS-Dilithium

Security Levels

ML-DSA-44, ML-DSA-65, ML-DSA-87 (equivalent to AES-128, AES-192, AES-256)

Performance

Fast signing and verification, larger key/signature sizes than classical algorithms

Key Sizes (ML-DSA-65):

Public Key

1,952 bytes

Secret Key

4,032 bytes
