How Router Encryption Works

In this video, I detail how your router encrypts its wireless traffic when communicating with devices in your network. The video above is included in the following blog post on network-from-home.com: https://network-from-home.com/does-a-... 0:00 Introduction 0:54 What communications router encryption protects 2:21 When router encryption is established between a router and a device 3:30 How encryption keys are established 5:25 How encryption keys are determined for multiple domains 6:05 How encryption keys are rotated 8:17 Other things to consider with router encryption 10:02 Conclusion What does router encryption protect? The important thing to understand about router encryption is the scope of its protection. Router encryption protects WiFi (wireless) communications between a device and a router. If a device has a wired connection to a router, router encryption is not used. This is because wired connections have less risk of being hacked. With WiFi communications, data is being sent through the air, which gives anyone the opportunity to listen in and capture this data. If your router didn’t encrypt these communications, anyone would be able to listen in on your communications with your router. How router encryption is established When you join a device to a router’s wireless network, you usually have to provide a password to get access to the network. Upon correctly providing the password for the WiFi network, your device is viewed as a trusted device by the router. After all, only trusted users and devices should have the password for the WiFi network. When devices are joined to the router’s WiFi network, the two devices will establish an encryption key to use for their communications. An encryption key is basically a decoder ring that’s used to scramble the communications that are sent over the air between the router and the device. Due to the fact that both devices have the decoder ring, they can scramble and unscramble the messages so they can read and respond to them. Other devices will be unable to understand the communications sent between the devices over WiFi because they don’t have the required decoder ring. Each device that connects to the router’s WiFi network will use a different decoder ring pair with the router to ensure that the device’s communications with the router can’t be snooped on by the other devices on the router’s network. On top of that (depending upon the encryption method being used by the router), the device and router will periodically rotate their decoder ring. In other words, after a set period of time, the router and device will change the encryption keys they’re using. That way, if a hacker somehow gets a hold of the encryption key that the router and device are using, they’ll only be able to read the messages between the two devices for a short period of time. I’m simplifying things here, but these are the basic concepts behind router encryption. Conclusion If you have any questions about how router encryption works, please leave a comment below.
