Line 7: Bob could designate a proxy to re-encrypt one of his messages that is to be sent to Chris. This generates a new [[Key (cryptography)\|key]] that Chris can use to decrypt the message. Now if Alice sends Chris a message that was encrypted under Bob's key, the proxy will alter the message, allowing Chris to decrypt it. This method allows for a number of applications such as [[e-mail forwarding]], law-enforcement monitoring, and content distribution. A weaker re-encryption scheme is one in which the proxy possesses both parties' keys simultaneously. One key decrypts a [[plaintext]], while the other encrypts it. Since the goal of many proxy re-encryption schemes is to avoid ~~revelaing~~revealing either of the keys or the underlying plaintext to the proxy, this method is not ideal. ==Defining Functions==
