| description | An electronic device according to an embodiment includes: a memory configured to store encryption information, a processor, and a switch configured to electrically disconnect the processor from the memory in a first state and to electrically connect the processor and the memory in a second state. The processor is configured to receive a user input for switching the switch from the first state to the second state, provide the encryption information stored in the memory to a secure application executing only in a second execution environment through a secure operating system of the second execution environment, when the switch is switched from the first state to the second state to generate an electrical path between the memory and the processor, acquire signature information for a transaction based on the encryption information, and provide the signature information acquired based on the encryption information to a signature request application. |
