Data security is one of the major challenges that prevent the wider acceptance of mobile devices, especially within business and government environments. It is non-trivial to protect private and sensitive data stored in these devices due to the limited resources and computing power, particularly when they fall in the hand of an adversary. Previously Chen and Ku proposed a lightweight data encryption and storage scheme named Self-Encryption (SE) to meet the challenge. However, the recent research revealed that there are critical weaknesses existing in SE.
