What is a man-in-the-middle attack?
What will be an ideal response?
A man-in-the-middle attack is used to intercept the transmission of a public key or even to insert a known key structure in place of the requested public key. Thus, attackers attempt to place themselves between the sender and receiver, and once they've intercepted the request for key exchanges, they send each participant a valid public key, which is known only to the attackers. To the victims of such attacks, their encrypted communication appears to be occurring normally, but, in fact, the attacker is receiving each encrypted message and decoding it (with the key given to the sending party), and then encrypting it and sending it to the originally intended recipient. Establishment of public keys with digital signatures can prevent a man-in-the-middle attack, as the attacker cannot duplicate the signatures.
