Techworld.com: WiFi fingerprints could end MAC spoofing
Read below for a new technique that may help to eliminate MAC spoofing on wireless networks. It remains to be seen how much processing power this may need once the process is refined.
Techworld.com - WiFi fingerprints could end MAC spoofing:
Every wireless device has a unique signal “fingerprint” produced by variations produced in the manufacturing process for silicon components, according to Dr Jeyanthi Hall, of Carleton University in Ottawa.
As a doctoral student, Dr Hall analysed the RF signals of fifteen devices from six manufacturers, and found it was possible to distinguish clearly, even between devices from the same manufacturer.
