Passive analysis of non-cooperative GSM signals
Paweł Skokowski, Krzysztof Kanciak, Jerzy Łopatka · 2009
In this paper we present methods enabling detection, interception and analysis of GSM signals including data cryptanalysis using passive methods. Presented procedures enable estimation of the signal basic parameters, identification of the transmission standard, signal demodulation and packet defragmentation. Next, cryptanalysis of intercepted data stream is performed.
