One of the key components of IEEE 802.11i authentication protocol to defend against various malicious attacks is its 4-way handshake scheme. However, since Message 1 in the handshake scheme has not been protected by the Message Integrity Code (MIC), the original 4-way handshake scheme specified by the IEEE standard is vulnerable to the Denial of Service (DoS) attacks and DoS flooding attacks. Several...
IEEE 802.11i standard offers arguably uncompromised confidentiality and integrity services by utilizing advance encryption standard in counter with cipher block chaining message authentication code protocol (AES CCMP). However the Nonce construction mechanism employed in the standard is weak, leading to Initial Counter prediction. Resultantly, the effective Key Length used for encryption is reduced...
