Análisis de seguridad de tecnologías inalámbricas de comunicación basado en radio definida mediante software

Abstract

Abstract:This research project develops a security analysis model oriented to some of the wireless communication technologies, such as Bluetooth, Wi-Fi, GSM and RKE. For the develop ment of the following work, four phases have been established: the investigation of exis ting wireless attack and defense methods, the comparison and selection of SDRs and the realization of passive and active attacks to the established wireless technologies, special emphasis is placed on the use of open access tools like GNU Radio and Wireshark, which together with the appropriate SDR devices, allow the realization of the selected attacks and the analysis of the impact caused by them. Once the attacks are executed, the Bluetooth and Wi-Fi security deficiencies are shown, where it is possible to discover important infor mation corresponding to the devices and the data exchanged in the connection. In addition, the weak security in GSM is verified, where it is possible to monitor the traffic and decode it. Finally, security tests on RKE shows that vehicles are vulnerable to replay attacks.
