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.

This driver implements a crypto API template that can be
|
|
instantiated either as a skcipher or as a 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)

Rijndael appears to be consistently a very good performer in

This is a generic implementation of AES that attempts to eliminate

data dependent latencies as much as possible without affecting
|
|
performance too much. It is intended for use by the generic CCM
|
|
and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
|
|
solely on encryption (although decryption is supported as well, but
|
|
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.

|
Organization of State Commercial Administration of China (OSCCA)
|
|
as an authorized cryptographic algorithms for the use within China.
|
|
|

SMS4 was originally created for use in protecting wireless

networks, and is mandated in the Chinese National Standard for

|
Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure)
|
|
(GB.15629.11-2003).

|
|
The latest SM4 standard (GBT.32907-2016) was proposed by OSCCA and

|
standardized through TC 260 of the Standardization Administration
|
|
of the People's Republic of China (SAC).
|
|

The input, output, and key of SMS4 are each 128 bits.
