Abstract
According to certain embodiments, an electronic device comprises: a memory storing an interface and an application; a processor; and a secure module physically separated from the processor and including a secure processor and a secure memory, wherein the processor is configured to: obtain user authentication information, through the interface; attempt user authentication, based on the user authentication information; obtain data stored in the secure memory when the user authentication succeeds; store a first token including a first valid duration for an access to the secure memory, the obtained data, and a first key value for decoding the obtained data in a buffer; and delete the first token and the first key value from the buffer when the first valid duration expires.
