This paper proposes a detection mechanism for such attacks. A cost function is defined using the low bandwidth usage characteristic and is calculated in a exponential weighted moving average manner to enable real-time detection of attack intervals. The detector is implemented in a simulation environment in a ₃G UMTS network and evaluated using metrics of interest such as: detection delay and probability of false positive and false negative detections. Finally, a simple attack mitigation technique is used together with the detector in a network under attack and manages to reduce the signaling load and end-to-end delay to the level of an unattacked network.]]> Tue 27 Mar 2018 14:03:59 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31645 Sat 24 Mar 2018 08:45:04 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31660 Sat 24 Mar 2018 08:44:47 AEDT ]]>
