26	Reason why “XOR” is a linear operation, but ordinary “addition” isn’t?
21	Why is the permutation in AES (and other ciphers) not random or key-dependent?
19	Why does only length prepending improve the security of CBC-MAC
16	How exactly is “true randomness” defined in the realms of cryptography?
10	Why is the DES s-box non-linear? Why does it make the cracking of the cipher more difficult?
