Figure 19.1: In public-key encryption [top], Alice encrypts a message using Bob’s public key, and Bob decrypts it using his private key. This scheme allows encrypted files to be sent in the absence of a secure means to exchange keys, a major improvement over symmetric encryption. It’s still possible, though, for Alice to receive a public key (or a conventional symmetric key) that ostensibly came from Bob, but that, in fact, belongs to a third party claiming to be Bob—the so-called man-in-the-middle attack (bottom).

Figure 19.2: Public key encryption allows Alice to verify that a message from Bob actually came from him and that it is unaltered from the original. Here’s how: Bob encrypts the hash value with his private key; encrypts the plaintext with Alice’s (green) public key; and sends both to her. Alice then decodes the received ciphertext using her own [orange] private key; decodes the hash value using Bob’s public key, thereby confirming the sender’s authenticity; and compares the decrypted hash value with one that she calculates locally on the just decrypted plaintext, thereby confirming the message’s integrity.
