1. A data encryption system, comprising:
a storage device adapted to store data D, the storage device including: an encryption/decryption module adapted to randomly generate a device key seed Sd according to a time interval between two specific operations on the storage device, and adapted to apply the generated device key seed Sd to data encryption of the data D, wherein the storage device is adapted to randomly generate the device key seed Sd in response to interrupts that notify the storage device of occurrence of the two specific operations.
