- If we choose two prime numbers p=13 and q=17in RSA (Rivest-Shamir-Adelman) algorithm,and choose Public Key = (p x q, e) = (221,5),
- Show the result andprocedures to generate Private Key. (5points)
(b) Show the procedures usingthe Public Key and the Private Key found in step(a) to encrypt a message M (Assume M=25); and to decrypt forobtaining the message.
Consider the following login protocol.
User knows password P
User knows Hash function H(.) and hasa mobile calculator
User gives login name N to machine
Machine generates random number R
Machine gives R to user
User computes X:= Hash(P)XOR Hash(R)
User gives X to
