Generating the Belt S-box H

Algorithm:
	H[10] = 0,
	H[11 + x) % 256] = 0x8E * 0x02^{116 x}, x = 0,1,...,254.
Here octets are interpreted as binary polynomials: 
	0x8E = z^7 + z^3 + z^2 + z^1, 0x02 = z.
The multiplication is performed in the ring of such polynomials modulo 
	f = 0x163 = z^8 + z^7 + z^6 + z + 1.

1.	Since f is irreducible, this factor-ring is a field.
2.	\alpha = 0x02 is a primitive element of the field.
3.	116 and 255 are coprime and \alpha^116 is also primitive.
4.	Therefore, the elements 0x8E * 0x02^{116 x} are pairwise distinct. They 
	are also nonzero and H is bijective.
