 480           Adiantum is a tweakable, length-preserving encryption mode
 481           designed for fast and secure disk encryption, especially on
 482           CPUs without dedicated crypto instructions.  It encrypts
 483           each sector using the XChaCha12 stream cipher, two passes of
 484           an ε-almost-∆-universal hash function, and an invocation of
 485           the AES-256 block cipher on a single 16-byte block.  On CPUs
 486           without AES instructions, Adiantum is much faster than
 487           AES-XTS.
 488
 489           Adiantum's security is provably reducible to that of its
 490           underlying stream and block ciphers, subject to a security
 491           bound.  Unlike XTS, Adiantum is a true wide-block encryption
 492           mode, so it actually provides an even stronger notion of
 493           security than XTS, subject to the security bound.

 501           Encrypted salt-sector initialization vector (ESSIV) is an IV
 502           generation method that is used in some cases by fscrypt and/or
 503           dm-crypt. It uses the hash of the block encryption key as the
 504           symmetric key for a block encryption pass applied to the input
 505           IV, making low entropy IV sources more suitable for block
 506           encryption.
 507
 508           This driver implements a crypto API template that can be
 509           instantiated either as an skcipher or as an AEAD (depending on the
 510           type of the first template argument), and which defers encryption
 511           and decryption requests to the encapsulated cipher after applying
 512           ESSIV to the input IV. Note that in the AEAD case, it is assumed
 513           that the keys are presented in the same format used by the authenc
 514           template, and that the IV appears at the end of the authenticated
 515           associated data (AAD) region (which is how dm-crypt uses it.)
 516
 517           Note that the use of ESSIV is not recommended for new deployments,
 518           and so this only needs to be enabled when interoperability with
 519           existing encrypted volumes of filesystems is required, or when
 520           building for a particular system that requires it (e.g., when
 521           the SoC in question has accelerated CBC but not XTS, making CBC
 522           combined with ESSIV the only feasible mode for h/w accelerated
 523           block encryption)

1602           (GB.15629.11-2003).
1603
1604           The latest SM4 standard (GBT.32907-2016) was proposed by OSCCA and
