Adiantum is a tweakable, length-preserving encryption mode |
|
designed for fast and secure disk encryption, especially on |
|
CPUs without dedicated crypto instructions. 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. |

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) |

with a more dramatic performance hit) |

Instead of using 16 lookup tables of 1 KB each, (8 for encryption and |
|
8 for decryption), this implementation only uses just two S-boxes of |
|
256 bytes each, and attempts to eliminate data dependent latencies by |

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

block. Interrupts are also disabled to avoid races where cachelines |

The Jitterentropy RNG is a noise that is intended |

to provide seed to another RNG. The RNG does not |

perform any cryptographic whitening of the generated |

random numbers. This Jitterentropy RNG registers with |
|
the kernel crypto API and can be used by any caller. |
