“…As wireless sensor networks are often required to satisfy the same properties, they sometimes integrate solutions first proposed in the peer-to-peer domain [10]. This is the case, in particular, for the family of WSN's designed around one of the most successful peer-to-peer designs, Distributed Hash Table (DHT) [5],used daily by millions of users through the BitTorrent protocol.…”

Abstract. Wireless Sensor Networks (WSN) are often deployed in hostile or difficult scenarios, such as military battlefields and disaster recovery, where it is crucial for the network to be highly fault tolerant, scalable and decentralized. For this reason, peer-to-peer primitives such as Distributed Hash Table (DHT), which can greatly enhance the scalability and resilience of a network, are increasingly being introduced in the design of WSN's. Securing the communication within the WSN is also imperative in hostile settings. In particular, context information, such as the network topology and the location and identity of base stations (which collect data gathered by the sensors and are a central point of failure) can be protected using traffic encryption and anonymous routing. In this paper, we propose a protocol achieving a modified version of onion routing over wireless sensor networks based on the DHT paradigm. The protocol prevents adversaries from learning the network topology using traffic analysis, and therefore preserves the context privacy of the network. Furthermore, the proposed scheme is designed to minimize the computational burden and power usage of the nodes, through a novel partitioning scheme and route selection algorithm.

“…WSN are therefore often deployed in hostile or difficult settings, such as battlefields or conflict areas, and are therefore required to be highly fault tolerant, scalable and decentralised. Because of this, WSN are increasingly designed around a distributed network structure and peer-to-peer primitives, to enhance scalability and resilience [7].…”

Access to information is crucial during conflicts and other critical events such as population uprisings. An increasing number of social interactions happen in the cyberspace, while information exchanges at the infrastructural level (monitoring systems, sensor networks, etc.) are now also based on Internet and wireless links rather than ad hoc, isolated wired networks. However, the nature of the Internet allows powerful hostile actors to block, censor, or redirect communication to and from specific Internet services, through a number of available techniques.Anonymity networks such as Tor provide a way to circumvent traditional strategies for restricting access to online resources, and make communication harder to trace and identify. Tor, in particular, has been successfully used in past crises to evade censorship and Internet blockades (Egypt in 2011, and Iran in 2012). Anonymity networks can provide essential communication tools during conflicts, allowing information exchanges to be concealed from external observers, anonymised, and made resilient to imposed traffic controls and geographical restrictions. However, the design of networks such as Tor makes them vulnerable to large-scale denial of service attacks, as shown by the DDoS targeted at Tor hidden services in March 2015.In this paper, we analyse the structural weaknesses of Tor with regard to denial of service attacks, and propose a number of modifications to the structure of the Tor network aimed at improving its resilience to a large coordinated offensive run by a hostile actor in a conflict scenario. In particular, we introduce novel mechanisms that allow relay information to be propagated in a distributed and peer-to-peer manner. This eliminates the need for directory services, and

“…As the task has multifaceted pedagogical objectives (none of which are explicitly programming related) we established the following requirements for the wireless sensor platforms used: the nodes should be programmable by the students using their existing language skills; the nodes should be capable of autonomous operation; the nodes should incorporate existing physical phenomena sensing capabilities; the node platform should include some standard data routing and dissemination algorithms (Mc Goldrick et al, 2009); the nodes should be capable of straightforward interfacing to external devices; the nodes should be capable of computing security and cryptographic primitives in "near" real time.…”

Purpose -The purpose of this study is to evaluate a practical laboratory task where final year undergraduate students design, implement and validate an inferred security wireless sensor access system. Design/methodology/approach -The quality of the learning and technical environment was evaluated from a number of perspectives using a mixed methods approach where both quantitative and qualitative data was collected and analysed. Two-tailed paired t-tests were used to analyse data on student performance, while a targeted survey was used to assess the achievement of the learning outcomes. The students' experience of working with the Sun Microsystems SunSPOTs was evaluated and the evolution of their perception of both ubiquity and security from inception to completion of the activity was explored. Findings -The results of this study indicate that the students' level of engagement with the assigned laboratory task was higher than with the two other forms of continuous assessment used on the module. Quantitative feedback gathered indicated that the learning outcomes were achieved, while the qualitative data indicated a high level of student satisfaction with the laboratory assignment. Originality/value -A novel wireless sensor network laboratory that encourages students to engage with the concepts of ubiquity and security is presented and evaluated.
