Using El-Gamal cryptosystem solve the following problems: 1. (ie, find C-(, , C) ) using the following Encrypt the message M- parameters: 30 PI primej ki randomj ci eipher 2. Suppose, in the above scenario, you want to sign the message M 10. What would be the signature (C1, C2) for the message M ? 3. Verify that the above signature you have found is correct (Compute (y * r* mod p) and (a" mod p).)
