Computer scientists in Japan say they've developed a way to break the WPA encryption
 

The attack gives hackers a way to read encrypted traffic sent between computers and certain types of routers that use the WPA (Wi-Fi Protected Access) encryption system. The attack was developed by Toshihiro Ohigashi of Hiroshima University and Masakatu Morii of Kobe University, who plan to discuss further details at a technical conference set for September 25 in Hiroshima.

Last November, security researchers first showed how WPA could be broken, but the Japanese researchers have taken the attack to a new level, according to Dragos Ruiu, organiser of the PacSec security conference where the first WPA hack was demonstrated. "They took this stuff which was fairly theoretical and they've made it much more practical," he said.

They Japanese researchers discuss their attack in a paper presented at the Joint Workshop on Information Security, held in Kaohsiung, Taiwan earlier this month.
