Verifiable Privacy-Preserving Range Query in Sensor Networks
نویسندگان
چکیده
We consider a sensor network that is not fully trusted and ask the question how we preserve privacy for the collected data and how we verify the data reply from the network. We explore the problem in the context of a network augmented with storage nodes and target at range query, a very general and powerful type of query. We use bucketization to mix the data for a range, use message encryption for data integrity, and employ encoding numbers to prevent the storage nodes from dropping data.

Collusion-Aware Privacy-Preserving Range Query in Tiered Wireless Sensor Networks†
Wireless sensor networks (WSNs) are indispensable building blocks for the Internet of Things (IoT). With the development of WSNs, privacy issues have drawn more attention. Existing work on the privacy-preserving range query mainly focuses on privacy preservation and integrity verification in two-tiered WSNs in the case of compromisedmaster nodes, but neglects the damage of node collusion. In th...

Privacy-preserving query has recently received considerable attention in the signal processing and multimedia community. It also is a critical step in wireless sensor network for retrieval of sensitive data. The purposes of privacy-preserving query in both the areas of signal processing and sensor network are the same but the similarity and difference of the adopted technologies are not fully e...
متن کاملSecure and Privacy Preserving Data Centric Sensor Networks with Multi-query Optimization
In large-scale Wireless Sensor Networks the effective use of the vast amounts of data gathered will require scalable, selforganizing, and energy-efficient data dissemination and data retrieval techniques. Data Centric Sensor (DCS) networks is a better approach in which the sensor nodes send the sensed data to a designated sensor node whose name is associated with sensed data. However, due to un...
