A Survey of WPA and 802.11i RSN Authentication Protocols
In the new standards for WLAN security, many choices exist for the authentication process. In this paper, we list eight desired properties of WLAN authentication protocols, survey eight recent authentication protocols, and analyze the protocols according to the desired properties.
متن کاملA Practical, Targeted, and Stealthy Attack Against WPA Enterprise Authentication
Wireless networking technologies have fundamentally changed the way we compute, allowing ubiquitous, anytime, any-where access to information. At the same time, wireless technologies come with the security cost that adversaries may receive signals and engage in unauthorized communication even when not physically close to a network. Because of the utmost importance of wireless security, many sta...
متن کاملDistinguishing WPA
We present an efficient algorithm that can distinguish the keystream of WPA from that of a generic instance of RC4 with a packet complexity of O(N), where N denotes the size of the internal permutation of RC4. In practice, our distinguisher requires approximately 2 packets; thus making it the best known distinguisher of WPA to date. This is a significantly improved distinguisher than the previo...
متن کاملWPA vs. WPA2: Is WPA2 Really an Improvement on WPA?
Significant weaknesses in the Wired Equivalency Protocol (WEP) led to the creation of the Wi-Fi Protected Access (WPA) Wired Local Area Network (WLAN) security protocol and the amendment to that protocol, WPA2. Certified by the WiFi Alliance in 2001, WPA[1] was superseded by WPA2 in 2006[1] as being mandatory for usage with the IEEE 802.11i standard for specifying security for wireless networks...
متن کاملWPA ? Is it possible ?
Wireless networks are commonly used by people. Market devices are equipped with the new security standard 802.11i. The standard announced in the middle of 2004 is commonly used to protect WLANs. Currently we can find the information that vulnerabilities were found in that standard. Then a question arises: Are WLANs compromised again? The article describes vulnerabilities which were discovered i...
