Over time, it was possible to make hardware acceleration for Elephant Diffuser as well, or at least give customers a choice between speed and security.Īnother, unofficial version looks more realistic. And the same AES was widely used even before there were separate instruction sets and specialized chips for its acceleration. However, in previous years, when processors were slower, for some reason the speed of encryption suited them. Vague explanations for this move followed after the simplifications in BitLocker were noticed by independent researchers.įormally, the removal of Elephant Diffuser was required to ensure Windows compliance with US Federal Information Processing Standards (FIPS), but one argument refutes this version: Vista and Windows 7, which used Elephant Diffuser, were sold without problems in America.Īnother imaginary reason for the refusal of the additional algorithm is the lack of hardware acceleration for Elephant Diffuser and the loss in speed when using it. People were simply given a weakened encryption technology with the same name under the guise of an update. At first, no official statements were made about this. So, in October 2014, Microsoft quietly removed the additional Elephant Diffuser algorithm, leaving only the AES-CBC scheme with its known shortcomings. However, BitLocker's key generation and encryption modes have changed. This general behavior of BitLocker continued in subsequent releases of Windows up until the present.
