Enhanced Wireless IEEE 802.11b Protocols Resistant to the Keystream Reuse Attack

Abstract

The security mechanism of IEEE 802.11b wireless network standard is the Wired Equivalent Privacy (WEP) protocol. The WEP can be used to protect communications from eavesdropping and other attacks. In fact an effective attack, called as keystream reuse attack, that aims at a public value initialization vector (IV) in WEP header is proposed. Here, we propose enhanced protocols resistant to the attack by lengthening the reuse cycle of IV.
