WPA Wi-Fi Encryption Cracked for the First Time Security researches say they've developed a way to partially crack the Wi-Fi Protected Access (WPA) encryption standard that is used to safeguard data on many wireless networks.
Researcher Erik Tews was to demonstrate the attack at the PacSec conference in Tokyo in mid-November. Cracking WPA encryption could be exploited to read data being sent from a router to a laptop, or to send bogus information to a cliŽent connected to the router.
Tews and' core searcher Martin Beck found a way to break the Temporal Key InŽtegrity Protocol (TKIP) key, which WPA uses, in a relaŽtively short 12 to 15 minutes, says Dragos Ruiu, the Pac Sec conference's organizer. In this particular attack, however, they have not managed to crack the encryption keys used to secure data sent from the PC to the router.
