This is version 2 of the block cipher NSABC. Version 1 was published on
Usenet July 2010.


I'm sorry for the typos. Here is a mini errata.

Relation:
G(x,(K0,K1),(L0,L1),C0) = ( ( x (o) K0 )S ^ C0) (o) K1 )S
where the first (o) is determined by its right unit L0,
and the second (o) similarly by L1.
