Again, the pre-shared key makes the encrypted data less dependent on hackable ciphers.Īlthough 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). As such, it can be useful in helping to resist brute force attacks where hackers are trying to break the encryption after successfully intercepting transmitted data packets. In the current context, the pre-shared key is a digital asset that unlocks the encrypted messaging sent over the network.

The code was not a cipher, then, but a reference to the pre-shared key itself. Without the underlying book, the pre-shared key, the set of numbers would defy analysis or code-breaking. The key could be delivered in person.Īfter that, the sender could send a set of numbers corresponding to an equidistant sequence matching the letters in the book. The key was often a book in which both the sender and receiver could measure equidistant letter sequence markings. One can think of some of the simple book ciphers of the early to mid-millennium where recipients used the pre-shared key to decode messages sent encrypted in the printed pages of a book. The idea is that users utilized an initial secure channel to deliver a key, and then subsequently at a future time, sent secondary transmissions where encryption depended on that initial key. The concept of a pre-shared key goes all the way back to primitive non-digital cryptography in prior centuries. One of the fundamental aspects of WPA-PSK security is the use of a pre-shared key. As a result, some telecom services have moved to using WPA instead of WEP protocol for encryption and authentication. Interestingly, both of these protocols use a pre-shared key, but the encryption on WEP is considered weaker than the encryption on WPA systems. It's important to note that WPA-PSK is one of multiple alternatives for this type of wireless LAN authentication and validation.Īnother one is called Wired Equivalent Protection (WEP). Unlike commercial WPA systems, the WPA-PSK method doesn't require a central server or various kinds of user-driven inputs. WPA-PSK can be used with the AES standard, which is a common standard in cybersecurity analysis. With a TKIP protocol, WPA-PSK uses 128-bit encryption. With WPA-PSK protocol, data transmission is encrypted and controlled using an end user’s generated password.
