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. 1277 1278 config CRYPTO_JITTERENTROPY_MEMSIZE_2 1279 bool "2048 Bytes (default)" 1280 1281 config CRYPTO_JITTERENTROPY_MEMSIZE_128 1282 bool "128 kBytes" 1283 1284 config CRYPTO_JITTERENTROPY_MEMSIZE_1024 1285 bool "1024 kBytes" 1286 1287 config CRYPTO_JITTERENTROPY_MEMSIZE_8192 1288 bool "8192 kBytes" 1289 endchoice 1290 1291 config CRYPTO_JITTERENTROPY_MEMORY_BLOCKS 1292 int 1293 default 64 if CRYPTO_JITTERENTROPY_MEMSIZE_2 1294 default 512 if CRYPTO_JITTERENTROPY_MEMSIZE_128 1295 default 1024 if CRYPTO_JITTERENTROPY_MEMSIZE_1024 1296 default 4096 if CRYPTO_JITTERENTROPY_MEMSIZE_8192 1297 1298 config CRYPTO_JITTERENTROPY_MEMORY_BLOCKSIZE 1299 int 1300 default 32 if CRYPTO_JITTERENTROPY_MEMSIZE_2 1301 default 256 if CRYPTO_JITTERENTROPY_MEMSIZE_128 1302 default 1024 if CRYPTO_JITTERENTROPY_MEMSIZE_1024 1303 default 2048 if CRYPTO_JITTERENTROPY_MEMSIZE_8192 1304 1305 config CRYPTO_JITTERENTROPY_OSR 1306 int "CPU Jitter RNG Oversampling Rate" 1307 range 1 15 1308 default 1 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. 1320 1321 config CRYPTO_JITTERENTROPY_TESTINTERFACE 1322 bool "CPU Jitter RNG Test Interface" 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.
