540 | Adiantum is a tweakable, length-preserving encryption mode | |
541 | designed for fast and secure disk encryption, especially on | |
542 | CPUs without dedicated crypto instructions. It encrypts | |
543 | each sector using the XChaCha12 stream cipher, two passes of | |
544 | an ε-almost-∆-universal hash function, and an invocation of | |
545 | the AES-256 block cipher on a single 16-byte block. On CPUs | |
546 | without AES instructions, Adiantum is much faster than | |
547 | AES-XTS. | |
548 | ||
549 | Adiantum's security is provably reducible to that of its | |
550 | underlying stream and block ciphers, subject to a security | |
551 | bound. Unlike XTS, Adiantum is a true wide-block encryption | |
552 | mode, so it actually provides an even stronger notion of | |
553 | security than XTS, subject to the security bound. | |

571 | help | |
572 | Encrypted salt-sector initialization vector (ESSIV) is an IV | |
573 | generation method that is used in some cases by fscrypt and/or | |
574 | dm-crypt. It uses the hash of the block encryption key as the | |
575 | symmetric key for a block encryption pass applied to the input | |
576 | IV, making low entropy IV sources more suitable for block | |
577 | encryption. | |
578 | ||
579 | This driver implements a crypto API template that can be | |
ab3d436b | 580 | instantiated either as an skcipher or as an AEAD (depending on the |
be1eb7f7 AB |
581 | type of the first template argument), and which defers encryption |
582 | and decryption requests to the encapsulated cipher after applying | |
ab3d436b | 583 | ESSIV to the input IV. Note that in the AEAD case, it is assumed |
be1eb7f7 AB |
584 | that the keys are presented in the same format used by the authenc |
585 | template, and that the IV appears at the end of the authenticated | |
586 | associated data (AAD) region (which is how dm-crypt uses it.) | |
587 | ||
588 | Note that the use of ESSIV is not recommended for new deployments, | |
589 | and so this only needs to be enabled when interoperability with | |
590 | existing encrypted volumes of filesystems is required, or when | |
591 | building for a particular system that requires it (e.g., when | |
592 | the SoC in question has accelerated CBC but not XTS, making CBC | |
593 | combined with ESSIV the only feasible mode for h/w accelerated | |
594 | block encryption) | |

1214 | This is a generic implementation of AES that attempts to eliminate | |

1219 | with a more dramatic performance hit) | |

1224 | prefetching the entire table into the cache at the start of each | |
