Tweakable Enciphering Schemes Using Only the Encryption Function of a Block Cipher
Palash Sarkar
Abstract
A new construction of block cipher based tweakable enciphering schemes (TES) is described. The major improvement over existing TES is that the construction uses only the encryption function of the underlying block cipher. Consequently, this leads to substantial savings in the size of hardware implementation of TES applications such as disk encryption. This improvement is achieved without loss in efficiency of encryption and decryption compared to the best previously known schemes.
