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

493 | help | |
494 | Encrypted salt-sector initialization vector (ESSIV) is an IV | |
495 | generation method that is used in some cases by fscrypt and/or | |
496 | dm-crypt. It uses the hash of the block encryption key as the | |
497 | symmetric key for a block encryption pass applied to the input | |
498 | IV, making low entropy IV sources more suitable for block | |
499 | encryption. | |
500 | ||
501 | This driver implements a crypto API template that can be | |
502 | instantiated either as a skcipher or as a aead (depending on the | |
503 | type of the first template argument), and which defers encryption | |
504 | and decryption requests to the encapsulated cipher after applying | |
505 | ESSIV to the input IV. Note that in the aead case, it is assumed | |
506 | that the keys are presented in the same format used by the authenc | |
507 | template, and that the IV appears at the end of the authenticated | |
508 | associated data (AAD) region (which is how dm-crypt uses it.) | |
509 | ||
510 | Note that the use of ESSIV is not recommended for new deployments, | |
511 | and so this only needs to be enabled when interoperability with | |
512 | existing encrypted volumes of filesystems is required, or when | |
513 | building for a particular system that requires it (e.g., when | |
514 | the SoC in question has accelerated CBC but not XTS, making CBC | |
515 | combined with ESSIV the only feasible mode for h/w accelerated | |
516 | block encryption) | |
