									  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

									  The Jitter RNG measures the execution time of memory accesses.
							 | 
						||
| 
								 | 
							
									  Multiple consecutive memory accesses are performed. If the memory
							 | 
						||
| 
								 | 
							
									  size fits into a cache (e.g. L1), only the memory access timing
							 | 
						||
| 
								 |

						||
| 
								 | 
							
									  the less variations are measured and thus the less entropy is
							 | 
						||
| 
								 | 
							
									  obtained. Thus, if the memory size fits into the L1 cache, the
							 | 
						||
| 
								 | 
							
									  obtained entropy is less than if the memory size fits within

								 | 
							
									  L1 + L2, which in turn is less if the memory fits into

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