34C3 - KRACKing WPA2 by Forcing Nonce Reuse

https://media.ccc.de/v/34c3-9273-krac... We introduce key reinstallation attacks (KRACKs). These attacks abuse features of a protocol to reinstall an already in-use key, thereby resetting nonces and/or replay counters associated to this key. We show that our novel attack technique breaks several handshakes that are used in a WPA2-protected network. Mathy Vanhoef https://fahrplan.events.ccc.de/congre...
