WPA and WPA2 encrypt data by using 48bits initial value, which is significantly more than WEP can offer. It’s implemented in almost all router models that came out over the past fifteen years. As a result, it quickly became the primary security standard for WiFi networks. This 802.11 WLANs security protocol addressed most of the weaknesses in WEP. Consequently, this algorithm was later replaced by a more advanced WPA protection. WEP is an aged type of WiFi encryption with a lot of critical vulnerabilities (low secret key value, poor key management, and weak value combinations). It encrypts the files that are being distributed across the network through the Open System and Shared Key authentication (OSA and SKA). This is a basic security algorithm for IEEE 802.11 standard. So, let’s begin with an introduction to wireless network authentication types.
