Microsoft SEAL — Fully Homomorphic Encryption as a Service
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
