WEP encryption for Wi-Fi hacked in 3 seconds: German researchers
The data encryption protocol in wireless networks Wi-Fi, WEP (“equivalent to wired privacy”), can be hacked in 3 seconds, according to three researchers from the University of Dotrmund, Germany. Demonstration of this process will take place at the weekend at a security conference in Hamburg.
The protocol is based on the RC4 encryption algorithm; Back in 2001, mathematicians said that it was theoretically unreliable, but for its opening it is necessary to send about 4 million packets. Later, new holes were found in the algorithm, which reduced the time for hacking into the search for a key - up to several hours. But the WEP algorithm remained robust in practice, since the keys changed every 5 minutes.
German researchers managed to extract a 104-bit WEP key in 3 seconds by intercepting wireless packets within a few minutes. This process can be repeated on any modern laptop: the experiment was carried out on a machine with a 1.7 GHz Pentium M processor. Moreover, hacking is also possible from less powerful handheld computers or smartphones, says one of the project participants, Eric Tews. ')
WEP was positioned as the “equivalent of wired network security,” where traffic between nodes cannot be intercepted.
