It encrypts each sector using the XChaCha12 stream cipher, two passes of an ε-almost-∆-universal hash function, and an invocation of the AES-256 block cipher on a single 16-byte block. On CPUs without AES instructions, Adiantum is much faster than AES-XTS. Adiantum's security is provably reducible to that of its underlying stream and block ciphers, subject to a security bound. Unlike XTS, Adiantum is a true wide-block encryption mode, so it actually provides an even stronger notion of security than XTS, subject to the security bound. If unsure, say N. config CRYPTO_ESSIV tristate "ESSIV support for block encryption" select CRYPTO_AUTHENC help Encrypted salt-sector initialization vector (ESSIV) is an IV generation method that is used in some cases by fscrypt and/or dm-crypt. It uses the hash of the block encryption key as the symmetric key for a block encryption pass applied to the input IV, making low entropy IV sources more suitable for block encryption. This driver implements a crypto API template that can be instantiated either as an skcipher or as an AEAD (depending on the type of the first template argument), and which defers encryption and decryption requests to the encapsulated cipher after applying ESSIV to the input IV. Note that in the AEAD case, it is assumed that the keys are presented in the same format used by the authenc template, and that the IV appears at the end of the authenticated associated data (AAD) region (which is how dm-crypt uses it.) Note that the use of ESSIV is not recommended for new deployments, and so this only needs to be enabled when interoperability with existing encrypted volumes of filesystems is required, or when building for a particular system that requires it (e.g., when the SoC in question has accelerated CBC but not XTS, making CBC combined with ESSIV the only feasible mode for h/w accelerated block encryption) comment "Hash modes" config CRYPTO_CMAC tristate "CMAC support" select CRYPTO_HASH select CRYPTO_MANAGER help Cipher-based Message Authentication Code (CMAC) specified by The National Institute of Standards and Technology (NIST). https://tools.ietf.org/html/rfc4493 http://csrc.nist.gov/publications/nistpubs/800-38B/SP_800-38B.pdf config CRYPTO_HMAC tristate "HMAC support" select CRYPTO_HASH select CRYPTO_MANAGER help HMAC: Keyed-Hashing for Message Authentication (RFC2104).
