Most wireless access points utilize one of the following three wireless security protocols:
1. WEP (Wired Equivalent Privacy)
2. WPA, also known as Wifi Protected Access
3. WPA2
Comparing the Differences Among Wifi Protocols WPA, WPA2, and WEP
WEP, also known as Wired Equivalent Privacy
WEP, also known as Wired Equivalent Privacy, stands as the initial wireless network security protocol. The first version of WEP was deemed insecure, employing 64-bit encryption, later replaced by the more secure WEP 256-bit encryption. However, 128-bit encryption still remains one of the widely applied standards.
WEP was once regarded as the ultimate network security protocol until security researchers discovered vulnerabilities allowing hackers to crack WEP in just a few minutes. WEP utilizes CRC, also known as Cyclic Redundancy Check.
WPA, also known as Wifi Protected Access
To address and overcome the shortcomings of WEP, WPA was developed as a new wireless network security protocol. WPA employs TKIP, also known as Temporal Key Integrity Protocol, to ensure the integrity of transmitted packets. This marks a significant change from WEP, which used CRC, also known as Cyclic Redundancy Check. In essence, TKIP is much safer than CRC.
Utilizing WPA ensures the integrity of transmitted data through a single encryption key. Combining encryption keys increases the complexity of decoding and reduces the risk of hackers collecting data or altering packets exchanged between the access point and the Wifi-enabled device.
However, similar to WEP, WPA also has security vulnerabilities, prompting the need for a more advanced Wifi protocol, leading to the emergence of WPA2.
WPA2 is the Wifi Protected Access 2
WPA2 currently stands as the most secure protocol. The significant difference between WPA and WPA2 lies in the use of the AES (Advanced Encryption Standard) and CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) algorithms, replacing TKIP.
CCM modes combine Counter (CTR) mode and Cipher Block Chaining Message Authentication Code (CBC-MAC) authentication, extensively researched and found to possess cryptographic properties, providing better security and performance for both software and hardware.
Above is the distinction among current popular security standards for setting Wi-Fi passwords: WPA, WPA2, and WEP.
