Wi-Fi Protected Access (WPA) encryption for wireless connections is considered a better and safer alternative than the older Wired Equivalent Privacy (WEP) standard that was cracked a long time ago. Security professionals may have to rethink their stance on WPA as researchers have developed a way to partially crack the encryption used. By 'partially', the researchers said they developed a way to intercept and read the data being sent from the router to a laptop computer but they have not yet been able to crack the encryption used to send the data from the computer to the router. The researchers, Erik Tews and Martin Beck, found a way to crack the Temporal Key Integrity Protocol (TKIP) key fairly quickly without using a dictionary attack. By tricking the router to send them a large amount of data, the research team developed what they call a “mathematical breakthrough” to crack the key in under 15 minutes. The newer WPA2 standard is believed to be safe from this method of attack.
