WPA (Wi-Fi Protected Access) keys, which offer a higher level of security than WEP keys but can still be compromised by determined hackers.
WPA2 (Wi-Fi Protected Access 2) keys, which are currently the most secure and widely used type of network security key.
WPA3 (Wi-Fi Protected Access 3) keys, which are the latest and most advanced type of network security key, offering enhanced security features and protection against modern threats.
How Network Security Keys Work
When you enter a network security key into a device, it is used to authenticate the device and establish a secure connection to the network. The key is encrypted and transmitted to the network router, which then verifies the key and grants access to the network if it is correct. This process is known as the four-way handshake, which involves the following steps:
The device sends an authentication request to the network router.
The router responds with a random number, known as a nonce.
The device uses the network security key to encrypt the nonce and sends it back to the router.
The router verifies the encrypted nonce and grants access to the network if it matches the expected value.
