Abstract
Embodiments of a secure multi-party computation method applicable to any computing node deployed in a distributed network are provided. A plurality of computing nodes is deployed in the distributed network. The plurality of computing nodes jointly participates in a secure multi-party computation based on private data respectively held by the computing nodes. The method includes: generating a computing parameter related to private data held by one computing node based on a secure multi-party computation algorithm; transmitting the computing parameter to other computing nodes participating in the secure multi-party computation for the other computing nodes to perform the secure multi-party computation based on collected computing parameters transmitted by the computing nodes participating in the secure multi-party computation; and creating an audit log corresponding to the computing parameter, the audit log recording description information related to the computing parameter.
