Optimal Green Hybrid Attacks in Secure IoT

Abstract

In pursuance to understand the behavior of a potential green hybrid attacker in secure internet-of-things (IoT), this letter investigates optimal energy utilization from the attacker's viewpoint. Specifically, we propose a novel framework for optimizing the efficacy of a hybrid attacker, possessing capability to both eavesdrop and jam, while considering the underlying energy consumption. In particular, we maximize the attacker energy efficiency (AEE) in secure IoT by deriving the analytical solutions for jointly global-optimal attacking mode, eavesdropping rate, and jamming power. Numerical results, validating analytical claims, reveal that the proposed green design can offer about 45% improvement in average AEE over the relevant benchmarks.

QoS‐aware stochastic spatial PLS model for analysing secrecy performance under eavesdropping and jamming

“…Similarly, Fig. 3, validates the analytical expression for PDF f log 2 (1+γ SU AU ) (c) given by (21) which also represents PDF of SCĈ J under jamming mode in high SNR regime, as explained in (32). Therefore, equivalent representation of PDF can be expressed as fĈ J (c).…”

“…The ongoing communication is assumed to be under security threat from a hybrid attacker with half‐duplex capability. It can over‐hear ongoing transmission as an eavesdropper through wiretapping or can act as a jammer causing interference to the information flow [17–19]. It is further assumed to be present within the deployment region with some statistical information about its location.…”

“…Apart from aforementioned works, studies in [19]- [21] exhibit a recent research interest on hybrid attackers that can either eavesdrop or jam. The authors have investigated the full duplex attacker in [22], [23] where passive eavesdropping and active jamming are performed simultaneously.…”

“…Moreover, most studies of stochastic networks consider a passive attacker that can only eavesdrop. Recently, the authors of [17–19] have shown the growing interest in hybrid attackers. However, the above‐mentioned works consider the deterministic path‐loss.…”

HARPAGON: An Energy Management Framework for Attacks in IoT Networks

“…This is why, studies on "green attacks" have emerged. In [10], [11], the authors focus on creating energy-efficient jamming attacks. In [10], authors create a model where the attacker estimates the distribution of the transmission period in the learning phase, and schedules its jamming attack according to this metric.…”
