Expert on a minute to kill Wi-Fi's method analysis of WPA encryption system

The following article is mainly about the security experts to kill Wi-Fi in a minute of the WPA encryption system, August 28 news, Japan's two security experts said they have developed a wireless router in a minute to break the WPA encryption system method. This attack provides hackers with the means to encrypt traffic between the computer and the routers that use WPA (Wi-Fi Protected Access) encryption systems. The attack was developed by two academics from Toshihiro Ohigashi of Hiroshima University, Japan, and Masakatu Morii of Kobe University, who are preparing to discuss the attack more thoroughly at a technical meeting held in Hiroshima on September 25. Last November, security researchers first disclosed a way to crack down on WPA, but Japanese academics have elevated the attack to new levels, said Dragos Ruiu, the organizer of the Pacsec security conference. "They have made it even more practical to do something that was quite theoretical at the time," he said. Two Japanese academics discussed the method in their paper, which was first read at the Joint Information Security Symposium (joint Workshop on Information), held in Kaohsiung, Taiwan, China, earlier this month. Last November's crack attack was developed by researchers Martin Beck and Erik Tews, which took about 12-15 minutes to complete the crack attack. Both of these attacks are only for WPA systems that use the TKIP (Temporary Key Integrity Protocol) algorithm, but are not effective for devices that have a newer WPA 2 system or that use a better cryptographic AES algorithm. The encryption system used by wireless routers has long been a security problem. The WEP (Wired Equivalent Privacy protection) system that emerged in 1997 was cracked several years later and was considered by security experts to be fundamentally unsafe. The WPA system, which uses the TKIP algorithm, "is only developed as a transitional encryption method," said Kelly Davis-felner, marketing manager for Wi-Fi Alliance. In her view, it would be better to use WPA 2. Enterprise-Class Wi-Fi networks typically have security software to detect man-in-the-middle attacks described by Japanese academics, said Errata Security's CEO Robert Graham. But the real and practical attack on WPA that the Japanese scholar has developed this time may give the enterprise reason to completely discard the TKIP algorithm's WPA system. "WPA is not as bad as WEP, but it's Dora," Graham said. "Users can switch from TKIP to AES using the management interface provided in many WPA routers. So as to ensure the safety of wireless networks.
