Answer the following: We would like to encrypt the message "HOWDY” using RSA. To do this, we will encrypt each letter individually (H = 8,0 = 15, W = 23, D = 4, Y = 25). Show detailed steps for at least one letter Use p = 17, q = 23, e = 3, m =(8, 15, 23, 4, 25)
Using RSA encryption with p=47, q=61, and e = 7, encrypt the following message in two-letter blocks: FAKE
4. Suppose you wish to encrypt the message, M 42 using RSA encryption. Given a public key where p- 23 and q-11 and the relative prime e- 7. Find n, and show all necessary steps to encrypt your message (42). (Hint: check p.411 of the text for information on public key RSA) (5 points)
In a RSA cryptosystem, a participant A uses two prime numbers p = 13 and q = 17 to generate her public and private keys. If the public key of A is 35, then the private key of A is 11. Alice wants to encrypt a message to Bob by using the RSA algorithm and using keys in (A) The plaintext = “HI”. Answer: _______________
