Question

diffie hellman protocol is susceptible to man in middle attack describe a solution to overcome this problem

Answer 1

ANSWER :-

"The Diffie-Hellman key exchange is vulnerable to a man-in-the-middle attack.

Possible solutions include the use of digital signatures and other protocol variants."with the appropriate key and transmitting them to the other party. This vulnerability is present because Diffie-Hellman key exchange does not authenticate the participants.

Solution :-The Diffie-Hellman protocol allows them to accomplish this even if an antagonist is monitoring their messages, as long as their secret information remains secret. The security of the protocol is based on the widely held belief that a certain computational number theory problem called the Diffie-Hellman protocol is sufficiently hard.
