Expert Solution & Answer
Chapter 1.4, Problem 4QE
Explanation of Solution
- “LeD or incandescent bulb”, is the device that can have two states, ON and OFF.
- When the current flows through the circuit, the bulb is ON and it indicates a high state.
- When the switch is OFF, there is no current in the circuit and the device is OFF and it indicates a low state.

Both encryption and decryption should output the different operation results for each round like the following: For example: Round 1: E(R0) = ......
