Abstract: A server intermediating federated learning, a user device, and a system including the server and the user device are disclosed. An intermediate server receives a global model from a central server to transmit the global model to a plurality of user devices. The intermediate server updates the global model based on a plurality of local models received respectively from the plurality of user devices in response to the transmission of the global model. One or more of the plurality of user devices includes a machine learning core to generate a local model by training the global model. The global model and individual data of a user device input into the machine learning core are encrypted or decrypted based on whether a key manager is comprised in the machine learning core.
