Abstract
An electronic device includes a temporary memory, a non-volatile memory and a processor. The temporary memory includes at least one secure region. The non-volatile memory is configured to store at least one higher-level secure program and a plurality of commands. The processor is connected to the temporary memory and the non-volatile memory for executing the plurality of commands to: when receiving a wake-up command, initialize the at least one secure region; and through the at least one higher-level secure program, recover the at least one secure region, or decrypt encrypted data stored in the non-volatile memory to recover the at least one secure region. In addition, a hibernation recovery method is also disclosed herein.
