12Wireless local area networks (WLAN) promise to be widely deployed in a short time, because they provide wire free connections with ease and with much higher transmission rates than current cellular systems. However, security holes have been identified in the operation of WLANs. The 802.11i protocol has been announced to protect the WLAN application area. However, there are still security issues such as a denial-of-service attack which can exhaust the client's memory using the vulnerability of a key derivation procedure in 802.11i. In this paper, the cookie mechanism is adopted to derive a solution to providing the required keys in a secure manner. We define a solution for our key derivation for 802.11i by providing encryption which can mitigate the denial-ofservice attack in 802.11i.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
