Secure multi-party computation method, device, apparatus and computer-readable storage medium

A secure multi-party computation device, comprising:

• one or more processors;
• and
• a storage device configured to store one or more programs, that, when executed by the one or more processors, cause the one or more processors to:
• dynamically convert a multi-party computation program segment into a first garbled circuit by using a multi-party computation operator of a first main body, and execute garbled gates of the first garbled circuit in sequence through an execution engine of the first main body, to encrypt data of the first main body;
• transmit to a second main body the encrypted data of the first main body and identifiers for garbled gates of the first garbled circuit;
• and
• perform a second encryption on the encrypted data of the first main body in sequence according to the received identifiers for the garbled gates of the first garbled circuit after the identifiers for the garbled gates of the first garbled circuit and the encrypted data of the first main body are received by the second main body, and return to the first main body a result of the second encryption on the encrypted data of the first main body.
