Tweakable Enciphering Schemes From Stream Ciphers With IV

Palash Sarkar

Abstract: We present the first construction of a tweakable enciphering scheme from a stream cipher supporting an initialization vector. This construction can take advantage of the recent advances in hardware efficient stream ciphers to yield disk encryption systems with a very small hardware footprint. Such systems will be attractive for resource constrained devices.
