Digital Signature using the RSA algorithm:  Alice is sending an integer value mA = 4 to Bob with RSA signing. Alice's have Public key: (5, 14) Private key: (11, 14). Alice first releases her public key to the public.  1) How to calculate the signature sig(mA).   2)  Later, Bob receives (mA, sig(mA)). Show how Bob verifies mA is from Alice. 3) Charlie, an attacker, sends a message mC = 12 to Bob and lets Bob believe mC is from Alice. mC’s digital signature sig(mC) is calculated using Charlie’s private key (7, 15). Show how Charlie computes sig(mC), and how Bob verifies whether it is from Alice or not (hint: Bob will use Alice’s public key).
