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.

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)

be used as a secure replacement for RIPEMD. For other use cases,

RIPEMD-160 should be used.

RIPEMD-160 (ISO/IEC 10118-3:2004).

RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
|
|
to be used as a secure replacement for the 128-bit hash functions
|
|
MD4, MD5 and it's predecessor RIPEMD
|
|
(not to be confused with RIPEMD-128).
|
|
|
|
It's speed is comparable to SHA1 and there are no known attacks
|
|
against RIPEMD-160.

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

are evicted when the CPU is interrupted to do something else.

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.
