591 without AES instructions, Adiantum is much faster than

593
594 Adiantum's security is provably reducible to that of its

596 bound. Unlike XTS, Adiantum is a true wide-block encryption

836 Encrypted Salt-Sector IV generator

838 This IV generator is used in some cases by fscrypt and/or
839 dm-crypt. It uses the hash of the block encryption key as the
840 symmetric key for a block encryption pass applied to the input
841 IV, making low entropy IV sources more suitable for block
842 encryption.
843
844 This driver implements a crypto API template that can be
845 instantiated either as an skcipher or as an AEAD (depending on the
846 type of the first template argument), and which defers encryption
847 and decryption requests to the encapsulated cipher after applying
848 ESSIV to the input IV. Note that in the AEAD case, it is assumed
849 that the keys are presented in the same format used by the authenc
850 template, and that the IV appears at the end of the authenticated
851 associated data (AAD) region (which is how dm-crypt uses it.)
852
853 Note that the use of ESSIV is not recommended for new deployments,
854 and so this only needs to be enabled when interoperability with
855 existing encrypted volumes of filesystems is required, or when
856 building for a particular system that requires it (e.g., when
857 the SoC in question has accelerated CBC but not XTS, making CBC
858 combined with ESSIV the only feasible mode for h/w accelerated
859 block encryption)

1250 CPU Jitter RNG (Random Number Generator) from the Jitterentropy library
1251
1252 A non-physical non-deterministic ("true") RNG (e.g., an entropy source
1253 compliant with NIST SP800-90B) intended to provide a seed to a
1254 deterministic RNG (e.g., per NIST SP800-90C).
1255 This RNG does not perform any cryptographic whitening of the generated
1256 random numbers.

1265 default CRYPTO_JITTERENTROPY_MEMSIZE_2
1266 help
1267 The Jitter RNG measures the execution time of memory accesses.
1268 Multiple consecutive memory accesses are performed. If the memory
1269 size fits into a cache (e.g. L1), only the memory access timing
1270 to that cache is measured. The closer the cache is to the CPU
1271 the less variations are measured and thus the less entropy is
1272 obtained. Thus, if the memory size fits into the L1 cache, the
1273 obtained entropy is less than if the memory size fits within
1274 L1 + L2, which in turn is less if the memory fits into
1275 L1 + L2 + L3. Thus, by selecting a different memory size,
1276 the entropy rate produced by the Jitter RNG can be modified.

1309 help
1310 The Jitter RNG allows the specification of an oversampling rate (OSR).
1311 The Jitter RNG operation requires a fixed amount of timing
1312 measurements to produce one output block of random numbers. The
1313 OSR value is multiplied with the amount of timing measurements to
1314 generate one output block. Thus, the timing measurement is oversampled
1315 by the OSR factor. The oversampling allows the Jitter RNG to operate
1316 on hardware whose timers deliver limited amount of entropy (e.g.
1317 the timer is coarse) by setting the OSR to a higher value. The
1318 trade-off, however, is that the Jitter RNG now requires more time
1319 to generate random numbers.

1323 help
1324 The test interface allows a privileged process to capture
1325 the raw unconditioned high resolution time stamp noise that
1326 is collected by the Jitter RNG for statistical analysis. As
1327 this data is used at the same time to generate random bits,
1328 the Jitter RNG operates in an insecure mode as long as the
1329 recording is enabled. This interface therefore is only
1330 intended for testing purposes and is not suitable for
1331 production systems.
1332
1333 The raw noise data can be obtained using the jent_raw_hires
1334 debugfs file. Using the option
1335 jitterentropy_testing.boot_raw_hires_test=1 the raw noise of
1336 the first 1000 entropy events since boot can be sampled.
