Question
Q8: In Cipher Block Chaining (CBC) mode, decryption is obviously the symmetric counterpart to encryption, because the inverse operations are used in the reverse order;
Q8: In Cipher Block Chaining (CBC) mode, decryption is obviously the symmetric counterpart to encryption, because the inverse operations are used in the reverse order; but in Counter (CTR) mode, decryption appears to be (almost) the same as encryption. Briefly explain why Counter mode is symmetric, despite this apparent contradiction.
