Abstract: With the rapid development of the Internet, data resources have become an important competitiveness of all industries. However, as the owners and users of data cannot beunified, problems such as data security and personal privacy become increasingly serious,resultingin the phenomenon of "data islands". Secure Multi-Party Computation (MPC)promises tosolve these problems by ensuring both privacy of data input and correctness of dataComputation, and by ensuring that data input from participating parties is not compromisedthrough protocols without third parties. Based on the definition and characteristics ofmulti-party secure computing, this paper introduces the research status, component model andapplication scenarios of multi-party secure computing.

Key words: multi-party secure computing, security model, personal privacy, cryptography, distributed computing
