Original Abstract Submitted
a method includes: receiving m scrambled models from m online service nodes; receiving descrambling secrets from t online service nodes, where a descrambling secret of any online service node is determined based on m first shared keys of the online service node corresponding to the m online service nodes and n−m second shared keys of the online service node corresponding to n−m offline service nodes; and determining an aggregated model, where disturbance vectors of the m scrambled models are determined based on the descrambling secrets from the at least t online service nodes, at least n−t+1 first subsecrets determined by each service node based on n first shared keys and a first disturbance item corresponding to the service node, and at least n−t+1 second subsecrets determined by the service node based on n second shared keys and a second disturbance item corresponding to the service node.
