Starting with Windows 10 version 1511, however, Microsoft added a new FIPS-compliant XTS-AES encryption algorithm to BitLocker. [1] Starting with Windows 10 version 1803, Microsoft added a new feature called "Kernel Direct Memory access (DMA) Protection" to BitLocker, to protect against DMA attacks via Thunderbolt 3 ports.
The Adiantum scheme used in low-end Android devices specifically chooses NH, 256-bit Advanced Encryption Standard (AES-256), ChaCha12, and Poly1305. The construction is tweakable and wide-block. It requires three passes over the data, but is still faster than AES-128-XTS on a ARM Cortex-A7 (which has no AES instruction set). [24]

For Data at Rest protection a computer or laptop is simply powered off. The disk now self-protects all the data on it. The data is safe because all of it, even the OS, is now encrypted, with a secure mode of AES, and locked from reading and writing. The drive requires an authentication code which can be as strong as 32 bytes (2^256) to unlock.

This should be acceptable for up to 2 64 × 16 B = 256 exabytes of data, and would suffice for many years after introduction. The winner of the AES contest, Rijndael, supports block and key sizes of 128, 192, and 256 bits, but in AES the block size is always 128 bits. The extra block sizes were not adopted by the AES standard.
AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. Most AES calculations are done in a particular finite field.
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008. [2] A wider version of AES-NI, AVX-512 Vector AES instructions (VAES), is found in AVX-512. [3]
