In Shared Key authentication, the WEP key is used for authentication in a four-step challenge–response handshake: The client sends an authentication request to the access point. The access point replies with a clear-text challenge. The client encrypts the challenge-text using the configured WEP key and sends it back in another authentication ...
The main purpose to implement TKIP was that the algorithm should be implementable within the capabilities of most of the old devices supporting only WEP. The initial authentication process is carried out either using a pre-shared key (PSK), or following an EAP exchange through 802.1X (known as EAPOL, which requires the presence of an ...
WEP used the RC4 algorithm for encrypting data, creating a unique key for each packet by combining a new Initialization Vector (IV) with a shared key (it has 40 bits of vectored key and 24 bits of random numbers). Decryption involved reversing this process, using the IV and the shared key to generate a key stream and decrypt the payload.
WPA2 has been found to have at least one security vulnerability, nicknamed Hole196. The vulnerability uses the WPA2 Group Temporal Key (GTK), which is a shared key among all users of the same BSSID, to launch attacks on other users of the same BSSID. It is named after page 196 of the IEEE 802.11i specification, where the vulnerability is discussed.
If you no longer have your Security Key, use these steps: Go to the Sign-In Helper. Sign in and go to the AOL Account Security page. Turn off Security Key 2-Step Verification. When you get your Security Key back or get a new key, you can re-enable 2-Step Verification in your Account Security settings.
Verified for iOS 9.3 and later. 1. Double press the Home button or swipe up and hold. 2. Swipe up on the image of the app. 3. Re-launch the app and attempt to reproduce the issue.
Unavoidably, however, pre-shared keys are held by both parties to the communication, and so can be compromised at one end, without the knowledge of anyone at the other. There are several tools available to help one choose strong passwords, though doing so over any network connection is inherently unsafe as one cannot in general know who, if ...
