Abstract
The present disclosure discloses a privacy-preserving computation method and apparatus for secure three-party matrix hybrid multiplication, and relates to the field of privacy-preserving computation technologies. The present disclosure focuses on a secure three-party matrix hybrid multiplication problem. Specifically, a secure two-party matrix multiplication protocol and a secure three-party matrix multiplication protocol are constructed. Then, a privacy-preserving computation request is obtained, and the privacy-preserving computation request is decoded to obtain a decoded privacy-preserving computation request. Finally, the secure two-party matrix multiplication protocol or the secure three-party matrix multiplication protocol is matched based on the decoded privacy-preserving computation request, to complete privacy-preserving computation of each participant. In this way, privacy-preserving computation can be implemented in a high-efficient, secure, and reliable manner. In addition, high coupling performance is achieved.
