How does wpa psk work

Although a pre-shared key and other aspects of WPA-PSK may be useful in this type of authentication system, the standard for authentication is moving from a simple password system to multi-factor authentication MFA. One of the most common methods is to use a smartphone as a secondary device authentication factor. The first WPA standard became available in A subsequent standard, WPA2, was introduced the next year.

A new WPA3 standard became available in By: Justin Stoltzfus Contributor, Reviewer. By: Satish Balakrishnan. Dictionary Dictionary Term of the Day. Natural Language Processing. Techopedia Terms.

For a detailed description it is best you refer to the RFC, as suggested before.

There are simplifying overviews, like this picture. Another helpful post might be this. This is not the actual key that is used for the encryption. Instead, you can use it to compute a secret session key without passing the session key on the wire. That is what the ANounce and SNounce are used for. Then, by sending encrypted messages in step 3 and 4 AP and station prove to each other they know the PMK.

If you share a secret with someone you can always use this to authenticate to each other and compute a session key. You simply generate a bit random number, send it to your partner encrypted with the secret. The partner decrypts it, increments by one and sends the message back again, encrypted. Then you verify what you get is what you sent plus one. Similar for generation of a session key. Both parties generate a random value, exchange it.

A keyword or password used for encrypting data or authenticating a network. Then it dynamically varies the encryption key. This is another name for the password on your modem or router. As mentioned above, a passphrase is a collection of common words combined together randomly into a phrase. Remember, an example of a passphrase is something like preachy glutton legislate shorter monsoon author.

The best passwords are ones that are 1 easy for you to remember and 2 hard for hackers to crack. Phase-shift keying PSK is a digital modulation process which conveys data by changing modulating the phase of a constant frequency reference signal the carrier wave. Action 2: If the network key PSK is correct, check the network connection.

WPA2-PSK requires a router with a passphrase, with a length between 8 to 63 characters, to encrypt the data in the network.
