Improvement of Dependability against Node Capture Attacks for Wireless Sensor Networks
A Wireless Sensor Network has sensor nodes which have limited computational power and memory size. Due to the nature of the network, the data is vulnerable to attacks. Thus, maintaining confidentiality is an important issue. To compensate for this problem, there are many countermeasures which utilize common or public key cryptosystems that have been proposed. However, these methods have problem...
متن کاملDistributed Detection of Node Capture Attacks in Wireless Sensor Networks
Wireless sensor networks are vulnerable to node capture attacks because sensor nodes are usually deployed in unattended manner. Once attacker captures sensor nodes, he can compromise them and launch various types of attacks with those compromised nodes. Therefore, node capture attacks are hazardous and should be detected as soon as possible to reduce the harm incurred by them. To meet this need...
متن کاملSecuring Node Capture Attacks for Hierarchical Data Aggregation in Wireless Sensor Networks
Serious security threat is originated by node capture attacks in hierarchical data aggregation where a hacker achieves full control over a sensor node through direct physical access in wireless sensor networks. It makes a high risk of data confidentiality. In this study, we propose a securing node capture attacks for hierarchical data aggregation in wireless sensor networks. Initially network i...
متن کاملModeling adaptive node capture attacks in multi-hop wireless networks
We investigate the problem of modeling node capture attacks in heterogeneous wireless ad hoc and mesh networks. Classical adversarial models such as the Dolev–Yao model are known to be unsuitable for describing node capture attacks. By defining the amortized initialization overhead cost as well as the cost of capturing a node, we show that finding the node capture attack yielding the minimum co...
متن کاملDependability of wireless sensor networks
As wireless sensor networks (WSNs) are becoming ever more prevalent, the runtime characteristics of these networks are becoming an increasing issue. Commonly, external sources of interference make WSNs behave in a different manner to that expected from within simplistic simulations, resulting in the need to use additional systems which monitor the state of the network. Despite dependability of ...
