Question:
You have found out that a bank sends money transfer messages encrypted with a onetime pad using XOR on bytes. You know that if you transfer $1000 from branch A to branch B, branch A encrypts and sends a message that says "Add 1000 dollars to Steve's balance." Explain, with as much detail as you can, how you can intercept and tamper with this message so that 9,999 dollars is added to my account instead of 1,000 dollars. [Hint: in one-time pad, a ciphertext C is computed as C=PK]
