<h1>Random Number Generation&nbsp;</h1>

<p>Random numbers might be generated by combining some pseudo-random sequence
generation function with bitstream from hardware based random bitstream
generator. The role of the pseudo-random sequence generation function is to
compensate for the slowness of the hardware based bitstream generator. The
hardware based bitstream generator might use light, sound, electrical noise <i>(even
regular electrical noise, like the 50Hz or some engine noise)</i> for an input
to some fast cryptographically relatively strong hash function <i>(not
unrollable, has collisions)</i>. The hash function output would be the random


<h1>Hash Function</h1>

<p>Probably one needs to write that from scratch, because 8bit MCUs are usually
not used for executing cryptographically strong hash functions. The
<a href="">MurMurHash</a> is not designed
to be cryptographically strong, but it might give some ideas.</p>
