The History of WPA2 Security Protocol
Understanding WPA2 history helps us see how wireless security has evolved. It was brought to life in 2004 to fix the flaws found in WEP (Wired Equivalent Privacy). This step changed how Wi-Fi networks were protected.
In 2003, the Wi-Fi Alliance put out WPA as a temporary fix. However, it soon got replaced by WPA2 in 2004 after WPA’s TKIP (Temporal Key Integrity Protocol) wasn’t enough. The new standard, WPA2, brought in AES (Advanced Encryption Standard) for stronger safety.
From March 13, 2006, all new gadgets had to pass Wi-Fi Alliance’s strict tests to use the Wi-Fi logo. This rule, lasting until June 30, 2020, made sure WPA2 was reliable.
In 2017, a big issue was found, called the Key Reinstallation Attack (KRACK). It showed that even the best security might have weak spots. Yet, WPA2 has stood strong against many online dangers.
By January 2018, the call for better protection brought WPA3 to the scene. It offers tougher security through new techniques like SAE (Simultaneous Authentication of Equals). Even so, WPA2 is still widely used, especially by businesses. It’s known for its strong encryption.
So, WPA2’s story is about constant growth in defending our wireless world. From overcoming WEP’s weaknesses to embracing new encryption tech, WPA2’s tale shows the endless push for safer connections.
