Karsten Nohl speaks about GSM: „The popular GSM cell phone standard uses outdated security and provides much less protection than its increasing use in security applications suggests. Our research aims to correct the disconnect between technical facts and security perception by creating a GSM tool that allows users to record and analyze GSM data to see what security features were really implemented by their operator. The talk discusses a GSM debugging tool that consists entirely of open source software and open radio hardware. We will demonstrate how to record and decode GSM calls, even encrypted ones.“

The talk was held at the DeepSec 2010 conference.
