Write at least 64 words explaining the minor problem with all public key ciphers

Write at least 64 words explaining the minor problem with all public key ciphers. For example, if someone sends you an encrypted message with their public key attached, the public key protects the message from eavesdroppers but fails to protect the message against someone else (who may be “in the middle”). Explain what is missing from public key ciphers. Because of this omission, explain the possible attack.
