Encryption hides the true content of network traffic from those without the decryption key. It takes an insecure communications technology, radio waves, and makes it secure. The original approach to solving this problem was a technology known as Wired Equivalent Privacy, or WEP. WEP was used for a long time, but it is now known to suffer from some very serious security vulnerabilities. And these issues are so significant that security professionals no longer consider WEP secure and it should never be used on a modern network. A newer technology called WiFi Protected Access, or WPA, replaced WEP all the way back in 2003. This first version of WPA, just called WPA, used the Temporal Key Integrity Protocol, or TKIP, to add security that WEP…
