370 | This is a generic implementation of AES that attempts to eliminate |
371 | data dependent latencies as much as possible without affecting | |
372 | performance too much. It is intended for use by the generic CCM | |
373 | and GCM drivers, and other CTR or CMAC/XCBC based modes that rely | |
374 | solely on encryption (although decryption is supported as well, but | |
375 | with a more dramatic performance hit) | |

f1f142ad RE |
377 | Instead of using 16 lookup tables of 1 KB each, (8 for encryption and |
378 | 8 for decryption), this implementation only uses just two S-boxes of | |
379 | 256 bytes each, and attempts to eliminate data dependent latencies by | |
380 | prefetching the entire table into the cache at the start of each | |
381 | block. Interrupts are also disabled to avoid races where cachelines | |
382 | are evicted when the CPU is interrupted to do something else. | |

885 | This driver implements a crypto API template that can be |
886 | instantiated either as an skcipher or as an AEAD (depending on the | |
887 | type of the first template argument), and which defers encryption | |
888 | and decryption requests to the encapsulated cipher after applying | |
889 | ESSIV to the input IV. Note that in the AEAD case, it is assumed | |
890 | that the keys are presented in the same format used by the authenc | |
891 | template, and that the IV appears at the end of the authenticated | |
892 | associated data (AAD) region (which is how dm-crypt uses it.) | |
1da177e4 | 893 | |
f1f142ad RE |
894 | Note that the use of ESSIV is not recommended for new deployments, |
895 | and so this only needs to be enabled when interoperability with | |
896 | existing encrypted volumes of filesystems is required, or when | |
897 | building for a particular system that requires it (e.g., when | |
898 | the SoC in question has accelerated CBC but not XTS, making CBC | |
899 | combined with ESSIV the only feasible mode for h/w accelerated | |
900 | block encryption) | |

1306 | help |
1307 | The Jitter RNG measures the execution time of memory accesses. | |
1308 | Multiple consecutive memory accesses are performed. If the memory | |
1309 | size fits into a cache (e.g. L1), only the memory access timing | |
1310 | to that cache is measured. The closer the cache is to the CPU | |
1311 | the less variations are measured and thus the less entropy is | |
1312 | obtained. Thus, if the memory size fits into the L1 cache, the | |
1313 | obtained entropy is less than if the memory size fits within | |
1314 | L1 + L2, which in turn is less if the memory fits into | |
1315 | L1 + L2 + L3. Thus, by selecting a different memory size, | |
1316 | the entropy rate produced by the Jitter RNG can be modified. | |

1349 | help |
1350 | The Jitter RNG allows the specification of an oversampling rate (OSR). | |
1351 | The Jitter RNG operation requires a fixed amount of timing | |
1352 | measurements to produce one output block of random numbers. The | |
1353 | OSR value is multiplied with the amount of timing measurements to | |
1354 | generate one output block. Thus, the timing measurement is oversampled | |
1355 | by the OSR factor. The oversampling allows the Jitter RNG to operate | |
1356 | on hardware whose timers deliver limited amount of entropy (e.g. | |
1357 | the timer is coarse) by setting the OSR to a higher value. The | |
1358 | trade-off, however, is that the Jitter RNG now requires more time | |
1359 | to generate random numbers. | |
