Find the key stream then encrypt the letter A by using A5/1 method, where the letter is given in ASCII code. The ASCII value for A is 65 = 1000001 0111011011 0 0 1 0 0 1 0 1 0 x noonnon 010 0 11 1 0 11 0 10V 1100110010111 0 0 1 1 0 0 0 0 1 0 z 2. Assume that you have the fallowing plain text: P-0110 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 1100 1101 1110 1100 And the key: K= 10010011 00110100 01010111 01111001 10011011 10111100 11011001 11110001 Encrypt P with K for only one round using the DES algorithm. Use the tables in the lecture notes. 3. Use the rail fence Cipher (3 rails) to encode the following plaintext: P= My name (write your name here) I live in (write you neighborhood here) 4. Encrypt the same plain text in 3 using the COLUMNAR algorithm with the key "alzahrani
