I am reading through this paper and one stage has got me stumbled:(adsbygoogle = window.adsbygoogle || []).push({});

http://www.cs.umbc.edu/~lomonaco/lecturenotes/9811056.pdf [Broken]

The part I don't understand is4.2.3 Phase 3 of Stage 2. Extraction of reconciled keyon page17.

I'm pretty sure this is purely mathematical stuff, so you don't need any knowledge of the quantum mess that surrounds it. I simply don't understand things like reconciliation, permutation, parity checks, etc. If someone could explain these ideas and that paragraph in general, or even just point to some place that does, I would be very grateful.

Thanks,
