Link-only posts aren't very helpful if the link moves. It's generally recommended that you summarize what the link has to say within the answer.

comment Random Galois fields
If you include the requirement that addition is implemented by bitwise xor, then all such representations have multiplications that can be implemented by a bitwise linear map of the two parameters, followed by a multiply within the $x^8+x^4+x^3+x+1$ representation, followed by another bitwise linear map (actually, the inverse of the first map). Hence, it doesn't appear that a random representation is any more 'nonaffine' than the standard one. How does inserting linear operations before/after the multiply make it less linear?

comment Can you help me with this Random Number Generator function?
LCG's are nonrandom, in the sense that they're easy to distinguish from a random permutation given just a few elements. Depending on what the permutation will be used for, Thomas's suggestion would be better (assuming that you can't hold the entire buffer in memory)
