Abstract: A fast disk encryption algorithm targeted at the specific application scenario of disk encryption is devised. The new algorithm is a tweakable cipher, and experimental results show that its performance is about 20% better than the algorithm adopted by Windows Vista Bitlocker Driver Encryption in software environment. The algorithm can provide the pseudo integrity protection ability.
