Finally, its detailed design, open-source availability, robustness, and superior performance when compared against competing solutions, make it a solution of choice in challenging EW scenarios, also paving the way to further research along the highlighted directions. Other than being completely tunable, BitTransfer can also enjoy further improvements by simply increasing the transmission rate of the devices. When under attack by a reactive jammer, BitTransfer can transfer a message of 127 Bit in 11.17 seconds, while competing approaches simply fail.
#Radio silence ex Bluetooth
To demonstrate its applicability to a wide class of commercial wireless devices, BitTransfer has been implemented using a real constrained hardware platform (the Openmote-b), released as freely available and open-source, and tested using the IEEE 802.15.4 communication technology, adopted within the Bluetooth and Zigbee 3.0 protocol stacks. In this paper we propose BitTransfer, an anti-jamming protocol enabling wireless communications between neighboring devices even under the above-described stringent requirements and powerful attacker model.īitTransfer embeds information bits in radio activity operations, a 0 being represented by the absence of any radio activity, and a 1 by the reception of a (corrupted) packet at the receiver. In such a challenging EW scenario, all the solutions currently available in the literature to mitigate reactive jamming require either the deployment of specialized hardware, or the modifications of physical layer protocols-the former solution being expensive, and the latter one usually not viable when considering commercially available wireless devices. Indeed, by first eavesdropping on the whole radio spectrum used for communications, and then timely injecting random noise as soon as a transmission is detected, reactive jamming represents both an effective and hard-to-detect attack tool. Reactive jamming techniques are especially suitable to this aim. Theoretical analysis and is supported by extensive experimental results,Įlectronic Warfare (EW) scenarios contemplate powerful and stealthy jamming attacks, able to disrupt any competing wirelessĬommunication in the target area. The on-the-fly communications and the 74% of the silent radio spectrum-whileĬompeting proposals simply fail.

With SiG it is possible to deliver a 128 bits long message with a probability The adversary capabilities, enabling the parties to communicate. Introducing a tunable, asymmetric communication channel, is able to mitigate Present Silence is Golden (SiG): a novel anti jamming protocol that, Under this powerful but yet realistic adversary model, the communicationīandwidth provided by current anti-jamming solutions drops to zero. We introduce a novel adversary model that has both (unlimited) jamming reactiveĬapabilities as well as powerful (but limited) proactive jamming capabilities. Paper we introduce several contributions to jamming mitigation. Their effectiveness in disrupting communications is unprecedented. Jamming techniques require just moderate resources to be deployed, while
