A provable, measurable secure computation device that enables privacy-preserving tensor operations using multi-party computation (MPC).
SPU (Secure Processing Unit) is a secure computation device that provides privacy-preserving tensor operations using multi-party computation (MPC). It enables computations on sensitive data without exposing the raw information, serving as the underlying engine for frameworks like SecretFlow to facilitate secure machine learning and data analysis.
Researchers and developers working on privacy-preserving machine learning, secure multi-party computation, and confidential data analysis who need a provably secure computation runtime.
SPU offers provable and measurable security guarantees through its MPC-based evaluation engine, making it a trusted foundation for building privacy-first applications without sacrificing computational capabilities.
SPU (Secure Processing Unit) aims to be a provable, measurable secure computation device, which provides computation ability while keeping your private data protected.

Implements a secure runtime with mathematically verifiable privacy using multi-party computation (MPC), ensuring data protection during tensor operations as highlighted in the README's focus on provable security.
Evaluates tensor operations compatible with XLA semantics, enabling efficient computation and seamless integration with frameworks like TensorFlow for privacy-preserving machine learning.
Provides guidelines and tools for experimental development, backed by peer-reviewed papers from conferences like USENIX ATC and ICML, making it ideal for academic exploration.
Developed with contributions from Alibaba Gemini Lab and security advisories from reputable sources, adding credibility and support for enterprise-level privacy applications.
The README explicitly warns that the SPU Python package's distributed module is not designed for production due to security and performance concerns, requiring reliance on SecretFlow for practical use.
Installation requires specific hardware features like AVX/ARMv8 and CUDA 11.8+ for GPU support, which can be a barrier for teams without specialized infrastructure or expertise.
Secure multi-party computation introduces significant computational and communication overhead, making it less suitable for high-performance or latency-sensitive applications compared to non-secure alternatives.
