How do I apply differential cryptanalysis to a block cipher?
I've read a lot of summaries of block ciphers particularly with regards to the NIST competitions stating that reduced-round block ciphers are, for example, vulnerable to differential cryptanalysis.
I ...

I read that we do not know if there exists an 8x8 sbox with differential uniformity = 2.
I suppose we cannot compute every possible sbox because there are $64!$ possible s-boxes. Am I right? Is ...
