Microsoft SEAL (Simple Encrypted Arithmetic Library) is an open-source homomorphic encryption library that enables computations on encrypted data without requiring decryption. The library supports two main encryption schemes: - BFV and BGV schemes for modular arithmetic operations on encrypted integers - CKKS scheme for approximate arithmetic operations on encrypted real or complex numbers Microsoft SEAL allows users to perform addition and multiplication operations directly on encrypted data, making it suitable for privacy-preserving computations in cloud environments. The library is written in modern C++ with no external dependencies required for basic functionality. Key features include: - APIs for key generation, encryption, decryption, and homomorphic operations - Batching capabilities for efficient processing of multiple values - Rotation operations for encrypted data manipulation - Serialization support for encrypted data storage and transmission - Optional integrations with Intel HEXL for performance optimization - Support for compression libraries like ZLIB and Zstandard The library can be compiled for multiple platforms including Windows, Linux, macOS, Android, iOS, and WebAssembly. Microsoft SEAL includes comprehensive documentation, code examples, and a separate compiler tool called EVA to simplify programming with the CKKS scheme. The project provides developers with tools to implement privacy-preserving applications where sensitive data needs to remain encrypted during processing operations.
