Reinstallation Attacks: Forcing Nonce Reuse in WPA2' was made publicly available. This paper discusses seven
vulnerabilities affecting session key negotiation in both the Wi-Fi Protected Access (WPA) and the Wi-Fi Protected
Access II (WPA2) protocols. These vulnerabilities may allow the reinstallation of a pairwise transient key, a
group key, or an integrity key on either a wireless client or a wireless access point. Additional research also
led to the discovery of three additional vulnerabilities (not discussed in the original paper) affecting wireless
supplicant supporting either the 802.11z (Extensions to Direct-Link Setup) standard or the 802.11v (Wireless
Network Management) standard. The three additional vulnerabilities could also allow the reinstallation of a
pairwise key, group key, or integrity group key.");
