Due to the unattended nature of wireless sensor networks, an adversary can capture and compromise sensor nodes, generate their replicas, and thus mount a variety of attacks with these replicas. Such attacks are dangerous because they allow the attacker to leverage the compromise of a few nodes to exert control over much of the network. Several replica node detection schemes have been proposed in the...
A number of protocols have been developed to mitigate the threat against wireless sensor networks of an attacker finding nodes, compromising them, and using these nodes to eavesdrop or undermine the operation of the network. A more dangerous threat that has received less attention, however, is that of replica nodes, in which the attacker compromises a node, extracts its keying materials, and produces...
We propose a multiuser quantum key distribution system based on entanglement property which is simple, more efficient, cost effective and easy to implement in laboratory environment. Existing protocols uses base communication to provide security, as 50% of the time sender and receiver's base is not agreed there are 50% bit loss during key distribution but our protocol does not need the base communication...
While multi-hop broadcast protocols, such as Trickle, Deluge and MNP, have gained tremendous popularity as a means for fast and convenient propagation of data/code in large scale wireless sensor networks, they can, unfortunately, serve as potential platforms for virus propagation if the security is breached. To understand the vulnerability of such protocols and design defense mechanisms against piggy-backed...
Conventional wireless sensor networks rely mostly on simple scalar data (such as temperature or humidity) and specialize in single-purpose applications. Taking a fundamental departure, in this article we motivate information-rich wireless video sensor networks that emulate the compound eyes found in certain arthropods. Although constrained by scarce resources, sensor nodes can only serve extremely...
This paper focuses on the assessment of the properties of security enforcement mechanisms for prevention of denial of service (DoS) attacks in wireless sensor networks. First part of the paper demonstrates the requirement for security enforcement using auction theory that allows detection of non cooperative nodes. In the proposed protocol, nodes prefer to participate in forwarding incoming packets...
