More Information
Summary:Disclosed is an electronic apparatus. The electronic apparatus according to the present invention comprises: a communication device which performs communication with an external device; a memory for storing data; and a processor which supports a trusted execution environment (TEE) function. The processor may: after receiving an open software, signature information corresponding to the open software, and hash information corresponding to the open software from an external device, store the received open software in a protection area corresponding to an SGX function; generate a secret key corresponding to the open software; and perform calculation corresponding to the open software by using the data and the open software stored in the protection area. Therefore, data leakage may be prevented. 전자 장치가 개시된다. 본 전자 장치는 외부 장치와 통신을 수행하는 통신 장치, 데이터를 저장하는 메모리, 및 TEE(Trusted Execution Environment) 기능을 지원하는 프로세서를 포함하고, 프로세서는 외부 장치로부터 공개 소프트웨어, 공개 소프트웨어에 대응되는 서명 정보 및 공개 소프트웨어에 대응되는 해시 정보를 수신하면, 수신한 공개 소프트웨어를 SGX 기능에 대응되는 보호 영역에 저장하고, 공개 소프트웨어에 대응되는 비밀 키를 생성하고, 보호 영역에 저장된 공개 소프트웨어 및 데이터를 이용하여 공개 소프트웨어에 대응되는 연산을 수행한다.
