WEP is an obsolete, flawed security algorithm for wireless networks. It uses RC4 encryption and CRC-32 checksum to provide data confidentiality and integrity, but has been deprecated since 2004 due to security vulnerabilities.
Wi-Fi Protected Access (WPA) is a security certification program for wireless networks developed by the Wi-Fi Alliance. It has three versions: WPA, WPA2, and WPA3, which use different encryption and authentication methods to protect data and prevent attacks.
IEEE 802.11i-2004 is an amendment to the original IEEE 802.11 standard, specifying security mechanisms for wireless networks. It replaces WEP with WPA2 and uses AES encryption, four-way handshake, group key handshake, and CCMP protocols.
AOSS (AirStation One-Touch Secure System) is a system that allows a secure wireless connection with the push of a button. It is used by some Nintendo, PlayStation and Wii devices and supports WEP, WPA and AES encryption.
TKIP is a security protocol for wireless networking that was designed to replace WEP without replacing legacy hardware. It uses key mixing, sequence counter, and message integrity check to protect against attacks, but is no longer considered secure and was deprecated in 2012.
Wi-Fi Protected Setup (WPS) is a network security standard to create a secure wireless home network. It allows users to connect devices to the Wi-Fi network without using any password, but has a security flaw that can be exploited by a remote attacker.
Learn about wireless security, the prevention of unauthorized access or damage to computers or data using wireless networks. Find out the common types of wireless security, such as WEP, WPA and WPA2, and the risks and countermeasures for wireless networks.
IEEE 802.11w-2009 is an amendment to the IEEE 802.11 standard that increases the security of its management frames. It provides data confidentiality, integrity, authenticity, and replay protection for some management frames using existing security mechanisms.
