The main purpose of a network security key is to encrypt the data transmitted over the network, ensuring that only authorized devices can access the network and its resources.
Types of Network Security Keys
There are several types of network security keys, including:
WEP (Wired Equivalent Privacy) keys, which are the oldest and least secure type of network security key. WEP keys are easily hackable and are no longer recommended for use.
WPA (Wi-Fi Protected Access) keys, which are more secure than WEP keys and use a protocol called TKIP (Temporal Key Integrity Protocol) to encrypt data.
WPA2 (Wi-Fi Protected Access 2) keys, which are the most secure type of network security key and use a protocol called AES (Advanced Encryption Standard) to encrypt data.
WPA3 (Wi-Fi Protected Access 3) keys, which are the latest and most secure type of network security key, offering enhanced security features and better protection against hacking.
How Network Security Keys Work
When you try to connect to a wireless network, your device sends a request to the network’s router, which then responds with a challenge. Your device must respond to this challenge with the correct network security key, which is then verified by the router. If the key is correct, the router grants your device access to the network. This process is called authentication, and it’s an essential step in securing your wireless network.
