Abstract: An electronic apparatus that writes encrypted data includes a first memory; a second memory configured to update encryption information including address information indicating a write location on the first memory and a parameter for use in encryption when data is encrypted and written to the first memory, and store the updated encryption information; an encryption and decryption unit configured to encrypt the data, based on the encryption information; and a processor configured to control the encrypted data to be written to the first memory, thereby increasing a safety level.
