Public key certificates prevent man-in-the-middle attacks by binding a user's public key to their identity via a digital signature from a trusted Certificate Authority (CA). An attacker cannot forge this signature without the CA's private key, ensuring that the recipient receives the genuine public key associated with the claimed identity.
Conditions: A trusted CA exists.; The recipient verifies the certificate using the CA's public key.
