a) Write down a possible condition of factors p and q. p= q= b) What is your private key SK: {d}? d= c) What is the plaintext of your friend’s message? The plaintext M = d) Suppose the plaintext M is a 12-digit number consisting of a prefix “19” and 1234567890. What is the corresponding ciphertext? Since M is greater than n, you only need to encrypt four digits at a time. Ignore redundant zeros. e.g., 0001 = 1. The result should contain three integers. The ciphertext C0 =
