In the Diffie-Hellman key exchange, each participant selects a secret number x and sends the other participant αx mod q for some public number α. What would happen if the participants sent each other αx for some public number α instead? Can Eve break your system without finding the secret numbers? Can Eve find the secret numbers? Describe three security requirements of a cryptographic hash function
