Which standard is not secure and should never be used on modern wireless networks?WEP was the first encryption protocol used to secure wireless networks and is now easily compromised and should never be used. TKIP shares many similarities with WEP encryption and is no longer considered secure. So it too should no longer be seriously considered when securing your network.
What standard is not secure and should never be used on modern wireless networks quizlet?What standard is NOT secure and should never be used on modern wireless networks? The Diffie-Hellman (DHE) algorithm is the basis for several common key exchange protocols, including Diffie-Hellman in Ephemeral mode (DHE) and Elliptic Curve DHE (ECDHE).
Which algorithm can they use to exchange a secret key?The Diffie-Hellman algorithm will be used to establish a secure communication channel. This channel is used by the systems to exchange a private key. This private key is then used to do symmetric encryption between the two systems.
When Patricia receives a message from Gary?When Patricia receives a message from Gary, she wants to be able to demonstrate to Sue that the message actually came from Gary. What goal of cryptography is Patricia attempting to achieve? Gary is sending a message to Patricia. He wants to ensure that nobody tampers with the message while it is in transit.
What is the only unbreakable cipher when it is used properly quizlet?What is the only unbreakable cipher when it is used properly? Explanation: The Vernam cipher, also known as a one-time pad, is unbreakable provided that the key is at least as long as the message and that each key is only used one time.
