Traditional cloud security
-
Cloud providers retain access to encryption keys and workloads
-
Compliance mandates require data sovereignty but today's infrastructure crosses borders
Quantum-Safe Confidential Computing
How sovereign is your cloud if your CSP still has access?
Arqit and Intel ensure everything entering or leaving your environment is quantum-safe encrypted and never exposed to the CSP.
The Data Sovereignty Challenge
Confidential compute is only half the solution
- Data in transit remains vulnerable outside the confidential enclave
- Hardware Security Modules (HSMs) add cost and complexity
- Keys stored or exchanged between environments create attack vectors
- No quantum-safe protection for data in use or in transit
Data Localization vs. AI Access
- Foreign governments can mandate cloud providers to reveal your encryption keys and sensitive workloads
- Data sovereignty mandates conflict with the need for AI compute resources abroad
Compliance and Liability Risks
- Institutions must comply with GDPR, PCI DSS, and CCPA while processing regulated data in multi-tenant cloud environments
- Without confidential computing, data remains visible to cloud operators - creating regulatory and legal exposure
Solution: Quantum-Safe Confidential Compute
Arqit NetworkSecure™ with Intel® Trust Domain Extensions delivers quantum-safe confidential computing - protecting data in use and in transit, even on shared infrastructure.
Key benefits for telcos and critical infrastructure providers:
Security & Data Sovereignty
- Quantum-safe encryption protects sensitive AI workloads and data from current and future threats
- Hardware-enforced isolation via Intel TDX ensures data-in-use protection even on shared infrastructure
- Ephemeral encryption keys generated inside trust domains are never exposed to cloud providers or third parties
- Full resilience against Harvest Now Decrypt Later (HNDL) attacks
- Attestation-verified trust domains prevent tampering and unauthorized access to confidential workloads
Compliance & Risk Mitigation
- GDPR, PCI DSS, and CCPA compliance through cryptographic data sovereignty - no foreign access to encryption keys
- Meets data localization mandates for institutions operating across jurisdictions
- Reduces regulatory risk by ensuring data remains under full institutional control
- Supports quantum-readiness requirements aligned with NIST and NSA post-quantum cryptography standards
Operational Efficiency & AI Enablement
- Lightweight software agent integrates seamlessly with existing cloud and on-premises infrastructure - no rip-and-replace
- Deploy confidential AI workloads on public cloud while maintaining complete control over data and keys
- Eliminates costly physical HSMs with virtual key management inside trust domains
- Enables secure cross-border collaboration and analytics without exposing sensitive data
- Future-proofs AI adoption for institutions facing strict data sovereignty requirements
Case Study
AI adoption demands data sovereignty – but how do you achieve both?
Financial institutions must leverage AI to remain competitive, yet strict data localization mandates under GDPR, PCI DSS, and national regulations prevent cross-border data access. Traditional cloud infrastructure exposes regulated customer data to foreign jurisdictions, creating compliance violations and regulatory risk.
Arqit and Intel TDX deliver quantum-safe confidential computing, ensuring encryption keys and sensitive workloads remain invisible to cloud providers – enabling AI adoption without compromising data sovereignty.
