Part 1: Five Tasks Locate an ascii chart on the Internet that shows the binary code for each character to use for this exercise. Using this extremely simplified ECB example of a substitution and transposition cipher given in the lecture on ciphers, complete the following cipher rounds (be sure to use XOR, not OR). We will begin with the plaintext byte: lower case s = 01110011 in ASCII binary as follows: L1 L2 L3 L4R1 R2 R3 R4 Plain Text 0 1 1 1 0 0 1 1 1. Show the next full substitution and transposition round using the information above if the next subkey is 1110: L1 L2 L3 L4 R1 R2 R3 R4 Plain Text 0 1 1 1 0 0 1 1 Subkey Apply Round Function to Rbits Round Function Result XOR with Lbits Swap halves 2. Starting from the last round, do the next full substitution and transposition round if the next subkey is 0001: L1 L2 L3 L4R1 R2 R3 R4 Plain Text Subkey Apply Round Function to Rbits Round Function Result XOR with Lbits Swap halves Part 1: Five Tasks Locate an ascii chart on the Internet that shows the binary code for each character to use for this exercise.
