I want to know how the nonlinear function of KeeLoq works.
Here at Wikipedia it says that:
The NLFSR feedback function is 0x3A5C742E
I understand that
F(a,b,c,d,e) = 3A5C742E.
Now, he did not say anything about encoding of
a, b, c, d, e. I consider them as in ASCII. But each letter will have 8-bit. So total would be 40. Could someone explains to me how to compute this function or what is the encoding scheme of
a, b, c, d, e in order to apply Karnaugh map?
