Suppose, B (the sender) wants to send a message to A. Before sending the message, B generates a digital signature. Assume that B and A use both of the public-key cryptography system and hash function when computing digital signatures. Say, the hash function used to compute and verify signatures is insecure, but the public-key cryptography system is secure. Show that T can forge signatures.
