The Diffie$-$Hellman key exchange is vulnerable to the following type of attack. An opponent Carol intercepts Alice's public value and sends $h$ When Bob transmits his public value, Carol substitutes it with her own and sends it to Alice. After this exchange, Carol simply decrypts any Bob, and then reads and possibly modifies them before re$-$encrypting with the appropriate key and transmitting them to the other party. Choose all the answers that are applicable to the above scenario.

The attack is called man$-$in$-$the$-$middle.
