Comparison of Block Cipher Modes
You may study the modes together, but please work out these answers on your own. Summative Grading Assignment.
Complete each question described below. When comparing blocks of ciphertext or plaintext, if corresponding blocks differ then mention which specific blocks differ. If they differ by only 1 bit, mention that fact specifically. If they differ by more than 1 bit, simply state the specific blocks that differ completely. If all blocks differ in the full ciphertext, simply state that there is no relationship. Be as precise as you can in your comparisons to illustrate that you understand the various modes.
