This question concerns block cipher modes. We will use a simple affine cipher, which can be expressed in C as follows. char cipher(unsigned char block, char key) { return (key+11*block)%256; } Note that the block size is 8 bits, which is one byte (and one ASCII character). We will work with the fixed key 0x08. We now encrypt various plaintexts using modes for this cipher. In every case in which the mode requires an IV, the IV will be 0xAA....

For the following question figure out what cipher was used to encode the following encrypted message. The text has been encrypted using one of the following ciphers (Caesar, Rail Fence, Vigenere, or Playfair): Fc risdzwche mrw gcne. Fvm xyxfi-xoeboc dcelqztaqcbizq. The key is also encoded: wsgmephmpiqqe (C+4) The key is : The message is: The key was encrypted using a cipher, which is a simple substitution cipher. The message was encoded using a cipher.

There is a simple encryption scheme that is called “Caesar Cipher”. In a “Caesar Cipher”, the letters in a message are replaced by the letters of a “shifted” alphabet. A “Caesar Cipher” encodes a message by shifting each letter in a message by a constant amount of k. If k is 5, A becomes F, B becomes G, C becomes H and so on. Let's use Queue to encode and decode the encrypt message. Set k as -5 and decipher...
