Abstract: A method of controlling an electronic device is provided. The method includes: identifying a first instruction for an encryption operation on a file using an encryption key; based on the first instruction being identified, obtaining the encryption key and metadata for the encryption operation and storing the obtained encryption key and the metadata in a non-volatile memory; and based on a user command for an access operation to the file being obtained, identifying the encryption key used for the encryption operation based on the metadata.

Abstract: According to an embodiment, an electronic device includes a memory, a first processor coupled to the memory and configured to control the electronic device in a normal execution environment (REE), and a second processor coupled to the memory and configured to control the electronic device in a secure execution environment (TEE). The first processor in the REE may be configured to transfer, to the second processor in the TEE, a request for generating a block including verification data of a data chunk. The second processor may be configured to generate the verification data of the data chunk by using key information of the electronic device, sign the verification data, and transmit, to an external electronic device, the block including the signed verification data.
