Pre-shared key can be defined as a client authentication technique that applies plain English passphrase in order to produce unique encryption keys. PSK is among the authentications methods applied in WPA2 and WPA authentication. However, you need to know that Pre shared key is not a default authentication technique used in the creation of WLAN service profile.
In the process of using network director, there are two different forms of encryption you will come across. The two forms are Wi-Fi protected Access and WPA 2. You can use PSK in the different forms of encryption we have outlined. WPA/WPA 2 enterprise is used to offer coverage for larger entities while WPA-PSK while WPA/WPA2 is applied in offering coverage to small and residential entities.
How do they work?
WPA allows you to configure different WLAN nodes client adapters as well as wireless router security system with the encryption key. With the help of Technology Key Integrity Protocol commonly referred to as you can generate different unique keys for your wireless router clients without going through much hassle over the same. The encryption keys can be changed from time to time. When your clients connect, the users will provide a password that helps them to determine if they can allow for network access or not. The client will be granted access as long as you ensure that the passwords are matching.
Why should you apply PSK authentication
PSK is meant for both small office and home networks systems, which do not need the application of a complex server. Some of the reasons why you should use PSK authentication include
Simple to implement- The authentication technique is simpler to implement when compared to 802.1X.
Some of your loyal clients might not support the 802.1 X or even the latest WPA 2 version.
Is there a difference between WPA PSK and WPA2 PSK?
Yes, there is. The main difference between the two is that encryption ciphers are applied when it comes to securing the network. WPA only uses TKIP but since TKIP keys are considered to be less secure, WPA 2 applies the advanced encryption standards for the same.
In addition, AES uses highly advanced algorithm that is easily defeated using tools that can overcome the TKIP security. This makes it to be a more secure option when compared to the others used in this field. Because WPA2 is the latest method, it is good to undertake firmware upgrades for those hardware that were using WPA only.
