Abstract
A method for operating an electronic device, and an electronic device, are provided. In the normal operation state of the electronic device, data which is stored in the main storage device of the electronic device is encrypted by a first encryption algorithm prior to being stored in a non-volatile storage device of the electronic device. The method includes the steps of generating snapshot data in the main storage device when the electronic device is entering a hibernation state, allocating space in the non-volatile storage device for storing the snapshot data, and storing the snapshot data in the space without encrypting the snapshot data using the first encryption algorithm.
