What is Wi-Fi encryption and how does it work?
Wi-Fi encryption is a security measure that scrambles the data transmitted between your device and the router, making it unreadable to unauthorized parties. It works by using an encryption protocol, such as WPA2 or WPA3, to encrypt the data before it’s transmitted over the airwaves. This ensures that even if someone intercepts the data, they won’t be able to read or access it without the encryption key.
The encryption process involves a handshake between your device and the router, where they exchange encryption keys and authenticate each other. Once the connection is established, all data transmitted over the Wi-Fi network is encrypted, providing a secure tunnel for your online activities. This prevents hackers from eavesdropping on your data, stealing sensitive information, orInjecting malware into your device.
