In the context of the ElGamal signature, the public key is (257, 76, x), where "x" is not known to you. Two packages were sent through the insecure channel as follows: (400, 54, 150) (321, 54, 149) Was there a re-use of the ephemeral key? If the answer is "yes", find it. If the answer is "no," answer "no" without the quotations.
