Haveged is a daemon process that complements/dev/random pools on Linux using volatile hardware entropy collection and extension algorithms adapted to the invention of the Irisa. The algorithm of the machine has tunes on the CPUID support itself, but also on the robot's test work 32 and 64-bit processors.
In practice, the collection sequence is computed by a branch, which reads the readout of the processor timestamp in an array because it permutes the contents of the array. The size of the data array is twice times the level 1 of the data cache and constructed so that the two-level cache block computes each output calculation. The calculation will be cyclical if there is no effect on the additional time stamp counter incrementing hardware unrelated events.
Haveged 1.2 Mainly improves the reliability of the daemon process.
