DATA PROCESSING METHOD AND APPARATUS EMPLOYING SECURE MULTI-PARTY COMPUTATION, AND ELECTRONIC DEVICE

摘要

A data processing method and apparatus employing secure multi-party computation, and an electronic device. The method comprises: determining whether or not a first privacy data matrix relating to a target matrix multiplication operation in a matrix multiplication operation sequence is the same as a second privacy data matrix or the transpose of the second privacy data matrix, the second privacy data matrix relating to a preceding matrix multiplication operation in the matrix multiplication operation sequence (S201); and if so, reusing the second privacy data matrix or the transpose thereof when performing the target matrix multiplication operation (S202). The method can improve the efficiency of data processing employing secure multi-party computation.
