Post-Quantum Cryptography for Cloud Providers.
Cloud providers are both primary HNDL targets and the infrastructure their enterprise customers depend on for cryptographic protection. FedRAMP, ISO 27001, and enterprise customer contract requirements are driving PQC migration expectations. Quantumize delivers the NIST-standardized algorithms and key management infrastructure cloud providers need to stay ahead of both adversaries and their customers.
Challenges
- Cloud Providers Hold Every Customer's Sensitive Data: A cloud provider's network traffic represents a cross-section of every customer's sensitive data making cloud infrastructure the highest-value single harvest target available. Every API call, storage read, and key management operation traversing classically encrypted channels is a candidate for collection and retroactive quantum decryption.
- Enterprise Customer PQC Requirements Are Landing in RFPs: Enterprise security teams are beginning to include post-quantum readiness requirements in cloud vendor RFPs, security questionnaires, and contract addenda. Cloud providers that cannot demonstrate ML-KEM and ML-DSA support will face competitive disadvantage in enterprise accounts with advanced security posture requirements.
- Key Management Service Migration Is the Critical Path: Cloud KMS is the root of trust for customer data encryption across every service. The classical keys these services protect are the primary target for HNDL attacks. Post-quantum key wrapping and KMS key migration tooling are the highest-priority capability cloud providers must offer their enterprise customers.
- FedRAMP and Government Customer Requirements: Cloud providers seeking FedRAMP High and DoD IL-4/5 authorization must align with post-quantum migration timelines tied to NSA CNSA 2.0 and OMB M-23-02. Government cloud customers will require demonstrated PQC migration capability as a condition of contract renewal in the near term.
Cloud Provider Compliance Framework
Cloud providers face a convergence of government authorization requirements, enterprise customer expectations, and international data protection mandates.
- FedRAMP: Federal Risk and Authorization Management Program authorization requirements are being updated to address post-quantum cryptographic migration for cloud providers serving federal agencies.
- DoD IL-4/5: DoD cloud Impact Level authorization requirements align with NSA CNSA 2.0 cloud providers seeking DoD IL-4/5 authorization must demonstrate post-quantum migration planning.
- ISO 27001: ISO 27001 cryptographic controls (Annex A.10) are being updated to address post-quantum readiness. ISO 27001 certification auditors are beginning to evaluate PQC migration plans.
- SOC 2 Type II: SOC 2 Trust Services Criteria for availability and confidentiality are being interpreted to include post-quantum cryptographic risk management. Enterprise customers are asking for SOC 2 evidence of PQC migration planning.
- NIST FIPS 203/204/205: The NIST-standardized post-quantum algorithms required for FedRAMP, DoD, and federal cloud authorization.
How Quantumize Helps
- Multi-Cloud KMS Post-Quantum Migration: Integrate with AWS KMS, Azure Key Vault, and GCP Cloud KMS all with post-quantum TLS to the key management service. Dry-run and live KMS key migration tooling re-wraps existing customer keys under post-quantum wrapping without service interruption.
- Customer Data Encryption With ML-KEM: Post-quantum encrypt customer data at rest and in transit with ML-KEM (FIPS 203). Envelope encryption with hardware-backed key wrapping and Cryptographic Recovery Packages (CRP) ensures permanent recoverability for all customer data.
- API and Service Authentication With ML-DSA: Sign API responses, software releases, and service attestation documents with ML-DSA (FIPS 204). Post-quantum digital signatures protect the authenticity of cloud service outputs for customers with long-lived audit requirements.
