A co-commitment based secure data collection scheme for tiered wireless sensor networks
نویسندگان
چکیده
Tiered wireless sensor networks (WSNs) have many advantages over traditional WSNs. However, they are vulnerable to security attacks, especially the attacks to the storage nodes that buffer and process the data readings from sensors. In this paper, we propose a secure data collection protocol SDC to support timebased queries in tiered WSNs. With small overhead introduced to data communication, SDC protects both data confidentiality and data integrity. In particular it employs data co-commitment scheme such that it can detect the seriousness of data losing and estimate the value of lost data in the network. 2010 Published by Elsevier B.V.

Hybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...

متن کاملAn efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...
متن کاملA Secure Routing Algorithm for Underwater Wireless Sensor Networks
Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
متن کاملUnauthenticated event detection in wireless sensor networks using sensors co-coverage
Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...
