Abstract

Windows Vista Enterprise and Ultimate editions use Bitlocker Drive Encryption as its disk encryption algorithm, and at its heart is the AES-CBC + Elephant diffuser encryption algorithm (ELEPHANT). In this paper we present our analysis of ELEPHANT using statistical tests. Our analysis has explored some weaknesses in its diffusers, thus we propose new diffusers to replace them. The new diffusers overcome the weaknesses of the original ones, and offer better and faster diffusion properties. We used the new diffusers to build variants of ELEPHANT, that possess better diffusion properties.
