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

501 | help | |
502 | Encrypted salt-sector initialization vector (ESSIV) is an IV | |
503 | generation method that is used in some cases by fscrypt and/or | |
504 | dm-crypt. It uses the hash of the block encryption key as the | |
505 | symmetric key for a block encryption pass applied to the input | |
506 | IV, making low entropy IV sources more suitable for block | |
507 | encryption. | |
508 | ||
509 | This driver implements a crypto API template that can be | |
ab3d436b | 510 | instantiated either as an skcipher or as an AEAD (depending on the |
be1eb7f7 AB |
511 | type of the first template argument), and which defers encryption |
512 | and decryption requests to the encapsulated cipher after applying | |
ab3d436b | 513 | ESSIV to the input IV. Note that in the AEAD case, it is assumed |
be1eb7f7 AB |
514 | that the keys are presented in the same format used by the authenc |
515 | template, and that the IV appears at the end of the authenticated | |
516 | associated data (AAD) region (which is how dm-crypt uses it.) | |
517 | ||
518 | Note that the use of ESSIV is not recommended for new deployments, | |
519 | and so this only needs to be enabled when interoperability with | |
520 | existing encrypted volumes of filesystems is required, or when | |
521 | building for a particular system that requires it (e.g., when | |
522 | the SoC in question has accelerated CBC but not XTS, making CBC | |
523 | combined with ESSIV the only feasible mode for h/w accelerated | |
524 | block encryption) | |

1597 | Organization of State Commercial Administration of China (OSCCA) | |
1598 | as an authorized cryptographic algorithms for the use within China. | |
1599 | ||
1600 | SMS4 was originally created for use in protecting wireless | |
1601 | networks, and is mandated in the Chinese National Standard for | |
1602 | Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure) | |
1603 | (GB.15629.11-2003). | |
1604 | ||
1605 | The latest SM4 standard (GBT.32907-2016) was proposed by OSCCA and | |
1606 | standardized through TC 260 of the Standardization Administration | |
1607 | of the People's Republic of China (SAC). | |
1608 | ||
1609 | The input, output, and key of SMS4 are each 128 bits. | |
