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 ...
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 anyone, may be eavesdropping on the interaction. Choosing keys used by cryptographic algorithms is somewhat different in that any pattern whatsoever should be avoided, as ...
In WPA2-protected WLANs, secure communication is established through a multi-step process. Initially, devices associate with the Access Point (AP) via an association request. This is followed by a 4-way handshake, a crucial step ensuring both the client and AP have the correct Pre-Shared Key (PSK) without actually transmitting it.
Key /Config-authentication is used to solve the problem of authenticating the keys of a person (say "person A") that some other person ("person B") is talking to or trying to talk to. In other words, it is the process of assuring that the key of "person A", held by "person B", does in fact belong to "person A" and vice versa.
If the values match, the authenticator acknowledges the authentication; otherwise it should terminate the connection. In PPP, the authenticator may send a new challenge at random intervals to the peer and repeats steps 1 through 3. However, when CHAP is used in most situations (e.g. RADIUS), this step is not performed.
1] EAP Pre-shared key (EAP-PSK), defined in RFC 4764, is an EAP method for mutual authentication and session key derivation using a pre-shared key (PSK). It provides a protected communication channel, when mutual authentication is successful, for both parties to communicate and is designed for authentication over insecure networks such as IEEE ...
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
