Abstract
Embodiments of a secure multi-party computation method applicable to any one computing node of a plurality of computing nodes deployed in a distributed network are provided. The plurality of computing nodes jointly participate in a secure multi-party computation based on private data held by each computing node. The computing node is connected to a trusted key source, and the method includes: obtaining a trusted key from the trusted key source; encrypting the private data held by the computing node based on the obtained trusted key to obtain ciphertext data; transmitting a computing parameter comprising at least the ciphertext data to other computing nodes participating in the secure multi-party computation, so that the other computing nodes perform the secure multi-party computation based on collected computing parameters transmitted by the computing nodes participating in the secure multi-party computation.
