Question - As is so often true in cryptography, it is easy to weaken a seemingly strong scheme by small modifications.

Suppose a variant of the OFB mode by which we only feedback the 8 most significant bits of the cipher output. We use AES and fill the remaining 120 input bits to the cipher with 0s.
