The main difference between the WEP and WPA2 protocols is the security of their encryption system, which is used to protect wireless networks. As of 2014, the WPA2 protocol uses an advanced encryption standard that provides high-level protection for files and network data. The WEP, on the other hand, is known to have exploitable loopholes and security flaws that reduce the safety of any network using it.
The WEP was the first security standard made available for wireless networks in 1999. The security protocol was developed with the aim of making wireless networks as secure as wired ones. It was released as part of the first IEEE 802.11 standard, and it utilized a 10- or 26-hexadecimal security key for protection.
The WPA2 is the second iteration of the Wi-Fi protected access security protocol, and it addresses security issues that resulted from the cipher that WEP utilized. The original WPA was a stop-gap security system created for wireless networks and devices that did not have WPA2-compatible hardware. As of 2014, the AIP standard used in the WPA2 safety protocol is used by the U.S. government to encrypt files that are classified as top secret. The WPA2 was first released in 2004 as part of the 802.11i wireless security standard.
