Abstract
Method for determining an extremum based on secure multi-party computation includes: acquiring a tmean obtained in tround federated computation; performing (t+1)round federated computation based on valid node data of an inode device in response to the valid node data of the inode device being greater than the tmean; performing the (t+1)round federated computation based on invalid node data in response to the valid node data of the inode device being less than or equal to the tmean; and determining that the valid node data of the inode device is the extremum in response to the valid node data of the inode device being greater than or equal to an (n−1)mean after (n−1)round federated computation.
