Exercise 1 (The RSA basics (
Alice forms a public key for the "textbook" RSA public-key encryption and signature schemes,
choosing N = 1073 and e = 715.
1. Encrypt the message M = 3 for Alice.
2. What is Alice's private key, and how does she use it for decrypting the received ciphertext?
3. Generate a signature on the message M = 1234567 using the following simple hash function
H: {0, 1} ZN such that H(M)= 3M + 5 (mod N).
4. Verify that the signature you generated in the previous step is a valid signature.
