“…The phase of a radar signal also contains target information. For examples moving-target indication (MTI) radars use the returned radar signal phase to determine whether the target is a moving or stationary object [2] and synthetic-aperture radars use the returned radar signal phase for imaging [3]. Therefore, it is important to modify both the frequency and phase of a radar signal to provide false target information to the hostile radar for electronic countermeasures.…”

A new microwave photonic signal processing structure that has the ability to realise frequency and phase shifting operation is presented. The proposed structure uses Serrodyne phase modulation in a dual-polarisation binary phase shift keying (DP-BPSK) dual-drive Mach Zehnder modulator to shift the frequency of an input microwave signal. This has the advantage over the conventional frequency mixers that the unwanted frequency components adjacent to the frequency translated microwave signal can be largely suppressed. It is suitable for use in deception jamming in electronic countermeasures systems. The phase shifting operation is realised by controlling the bias voltages of the DP-BPSK modulator. The dual-function microwave photonic signal processor has a simple structure and a wide bandwidth. The structure enables commercial modulator bias controllers to be used to provide long-term stable performance. Experimental results are presented that demonstrate a wide operating frequency range of 3 to 16 GHz, an over 35 dB suppression on the spurious signals and 0°to 360°phase shift on the frequency translated microwave signal. Using bias controllers to maintain a large spurious suppression ratio of around 35 dB is also demonstrated.

“…The initiation of the BitTransfer scheme is tied to the strategy to detect an ongoing jamming attack on the communication link between two neighboring devices. Jamming detection involves a few effective strategies, already discussed in the literature and outside the scope of the proposed protocol (see, for instance, [36], [37], and [38]). All these techniques are perfectly suitable for integration with BitTransfer.…”

Electronic Warfare (EW) scenarios contemplate powerful and stealthy jamming attacks, able to disrupt any competing wireless communication in the target area. Reactive jamming techniques are especially suitable to this aim. 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. 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. 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. BitTransfer 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. 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. When under attack by a reactive jammer, BitTransfer can transfer a message of 127 Bit in 11.17 seconds, while competing approaches simply fail. Other than being completely tunable, BitTransfer can also enjoy further improvements by simply increasing the transmission rate of the devices. 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.

“…Mitigating the presence of a jammer in WSNs is a well-known topic. While some recent contributions focused on detecting a reactive jammer [ 4 , 5 , 6 ], only a few of them proposed solutions to still allow communications in such a scenario.…”

Strength of Crowd (SOC)—Defeating a Reactive Jammer in IoT with Decoy Messages

We propose Strength of Crowd (SoC), a distributed Internet of Things (IoT) protocol that guarantees message broadcast from an initiator to all network nodes in the presence of either a reactive or a proactive jammer, that targets a variable portion of the radio spectrum. SoC exploits a simple, yet innovative and effective idea: nodes not (currently) involved in the broadcast process transmit decoy messages that cannot be distinguished (by the jammer) from the real ones. Therefore, the jammer has to implement a best-effort strategy to jam all the concurrent communications up to its frequency/energy budget. SoC exploits the inherent parallelism that stems from the massive deployments of IoT nodes to guarantee a high number of concurrent communications, exhausting the jammer capabilities and hence leaving a subset of the communications not jammed. It is worth noting that SoC could be adopted in several wireless scenarios; however, we focus on its application to the Wireless Sensor Networks (WSN) domain, including IoT, Machine-to-Machine (M2M), Device-to-Device (D2D), to name a few. In this framework, we provide several contributions: firstly, we show the details of the SoC protocol, as well as its integration with the IEEE 802.15.4-2015 MAC protocol; secondly, we study the broadcast delay to deliver the message to all the nodes in the network; and finally, we run an extensive simulation and experimental campaign to test our solution. We consider the state-of-the-art OpenMote-B experimental platform, adopting the OpenWSN open-source protocol stack. Experimental results confirm the quality and viability of our solution.
