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.

Abstract: An electronic device according to an embodiment includes a first random number generator module, a second random number generator module, a buffer memory configured to store random number data, and a processor configured to be operatively connected to the first random number generator module, the second random number generator module, and the buffer memory, wherein the processor is configured to acquire a first random number sequence from the first random number generator module to store the acquired first random number sequence in the buffer memory, generate a third random number sequence obtained by changing the first random number sequence based on a second random number sequence acquired from the second random number generator module, and generate an encryption key based on the third random number sequence. In addition, various other embodiments are possible.
