WPA Goes Down: Researchers Claim One-Minute Crack

It’s been known for years that the Wired Equivalent Privacy or
WEP
protocol is easily broken, and that to
be secure, wireless networks should use the more powerful protocol called Wi-Fi Protected
Access, or WPA.

Now security experts say they’ve proven that WPA can be breached just as easily. A
pair of researchers in Japan said that they developed a way to break WPA encryption in
about one minute — and will show how at a conference there next month.

WPA’s viability has been in doubt since late 2008, when security researchers Martin
Beck and Erik Tews demonstrated the ability
to break the Temporal Key Integrity Protocol (TKIP) that provides WPA security within 15
minutes.

Now, Researchers Toshihiro Ohigashi of Hiroshima University and Masakatu Morii of Kobe
University said they’ve improved on that. The pair has already discussed their findings
in a paper presented
at the Joint Workshop on Information Security held in Taiwan earlier this month and will
discuss it again at a
Sept. 25 event in Hiroshima. Read the rest at InternetNews.com.
