Abstract: An apparatus and a method for updating firmware by using a security integrated circuit in an electronic device. An electronic device may include a security integrated circuit (IC) providing a rich execution environment and a secure execution environment. The security integrated circuit includes a main processor operating in the rich execution environment and a secure processor operating in the secure execution environment. The secure processor is configured to perform user authentication based on firmware update information received from a server through the main processor. If the user authentication is successful, authentication information is generated corresponding to the firmware update information and stored in at least a part of a secure memory. If the firmware is installed, authentication of the firmware is performed based on the authentication information stored in the secure memory, and if the authentication of the firmware is successful, the firmware is installed.

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.
