Abstract: An electronic apparatus includes a communication interface, a memory; and a processor. The memory is configured to store a hypervisor. The processor is configured to obtain an authentication key for performing authentication of an external device. The processor is also configured to encrypt the authentication key based on a key pre-stored in the memory using the hypervisor and store the encrypted authentication key in the memory. Based on a request for information that is stored in the memory being received from the external device, the processor is configured to perform authentication of the external device using the hypervisor. Based on the authentication of the external device being completed, the processor is configured to control the communication interface to transmit the stored information to the external device.

Abstract: A server is provided. The server according to an embodiment includes a memory, a communicator, and a processor configured to transmit an application check module for identifying integrity of an application stored in an electronic apparatus to the electronic apparatus through the communicator, and, based on identification information corresponding to the application being received from the electronic apparatus, identify integrity of the application based on the received identification information, wherein the processor is further configured to identify integrity of the application based on whether the received identification information is signed by a signature key included in the application check module, and whether the received identification information matches identification information that is pre-stored in the memory.
