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]
Key management takes place within the hard disk controller and encryption keys are 128 or 256 bit Advanced Encryption Standard (AES) keys. Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid ...
The extra block sizes were not adopted by the AES standard. Many block ciphers, such as RC5, support a variable block size. The Luby-Rackoff construction and the Outerbridge construction can both increase the effective block size of a cipher. Joan Daemen's 3-Way and BaseKing have unusual block sizes of 96 and 192 bits, respectively.
For AES-128, the key can be recovered with a computational complexity of 2 126.1 using the biclique attack. For biclique attacks on AES-192 and AES-256, the computational complexities of 2 189.7 and 2 254.4 respectively apply. Related-key attacks can break AES-256 and AES-192 with complexities 2 99.5 and 2 176 in both time and data ...
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]

Serpent is a symmetric key block cipher that was a finalist in the Advanced Encryption Standard (AES) contest, in which it ranked second to Rijndael. [2] Serpent was designed by Ross Anderson, Eli Biham, and Lars Knudsen. [3] Like other AES submissions, Serpent has a block size of 128 bits and supports a key size of 128, 192, or 256 bits. [4]
