Multiparty computation method based on block chain, apparatus, electronic apparatus, non temporary computer readable storage medium, and computer program

摘要

Problem to be solved: to provide a solution that achieves both safety and reliability of multi party data.A target server selecting method executed by the participant apparatusHow to obtain business data ciphertext by encrypting business dataHashing business data ciphertextGet the business data hash result andBy sending a business data hash result to a block chain nodeInstruct a block chain node to write a business data hash result to a block chain andBy sending a business data ciphertext to the target treble calculation module in the target serverInstruct the target ordered computation module to perform multi party computation based on the business data hash results in the business data ciphertext and block chain;.Diagram
