Increasing base-station anonymity through illusive void formation

Energy-Aware Cross-Layer Technique for Countering Traffic Analysis Attacks on Wireless Sensor Network

“…To mitigate such a threat, many countermeasures are proposed to prevent, or at least delay, an adversary from locating the BS. Many of these countermeasures aim to change the traffic pattern in the network to confuse the adversary [12], [13], [14], [15], [16], [17], [18], [19], [20], [21]. Others, e.g., [13], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], and [33] introduce extra fake packets to hide the data routes and hence lead the adversary to wrong locations.…”

“…An adversary would aim at identifying the role, location, and identity of WSN nodes to gain knowledge about the structure of the network and distinguish vital assets that could be attacked [39], [40]. Therefore, privacy and security in WSN has received a lot of attention from the research community [9], [10], [11], [12], [13], [14], [22], [26], [27], [28], [29], [30], [31], [41], [42], [43]. Particularly, concealing the role and location of BS is deemed to be more crucial [9], [44].…”

“…Generally, boosting the delays is not suitable for time sensitive applications. In [14], geographic routing is altered in the BS vicinity to give the illusion of a void. Route alteration is achieved through careful node selection on the boundary of the illusive void region so that their transmission reaches the BS.…”

Traffic Analysis Through Spatial and Temporal Correlation: Threat and Countermeasure

“…FIVA [13] exploits the effect of a void on geographic routings to form a routing topology that mimics the presence of a void region surrounding the BS. Therefore, the adversary would shift its attention away from the void region that the BS is residing in.…”

A multi-illusive voids approach for increasing base station anonymity

“…These countermeasures pursue strategies on the physical, link and network layers of the communication protocol stack. In [7], we have proposed FIVA (Formation of Illusive Void for increased BS Anonymity) which strives to confuse the adversary by forming a fake void around the BS in order to give the illusion that there are no nodes in the BS vicinity and no packets are forwarded. The BS still receives the data through designating one node as a Covert Gateway (CG).…”
