homomorphic-encryption • Security & Privacy
Microsoft SEAL enables computation on encrypted data without ever decrypting it. Enterprises can run analytics, ML inference, and database queries on ciphertext — meaning sensitive data (health records, financial data, government intel) is never exposed during processing. Now available as a managed cloud service.
Features
- •BFV and CKKS schemes for exact and approximate arithmetic on encrypted data
- •Encrypted machine learning inference with <10x overhead vs plaintext
- •Database query evaluation on encrypted columns (WHERE, SUM, COUNT)
- •Multi-party computation combining homomorphic and secret sharing
- •Hardware acceleration on Intel HEXL and NVIDIA CUDA backends
- •Managed service with key management and audit logging
Benefits
- •Process regulated data without compliance exposure
- •Enable cross-organizational analytics without data sharing
- •Cloud provider never sees plaintext — zero trust by mathematical proof
- •HIPAA/GDPR compliant analytics on encrypted patient/customer data
- •DARPA and intelligence community proven — now enterprise ready
