Privacy- and Integrity-Preserving Range Queries in Sensor Networks

Privacy- and Integrity-Preserving Range Queries in Sensor Networks

Abstract:

The architecture of two-tiered sensor networks, where storage nodes serve as an intermediate tier between sensors and a sink for storing data and processing queries, has been widely adopted. We propose SafeQ, a protocol that prevents attackers from gaining information from both sensor collected data and sink issued queries. SafeQ also allows a sink to detect compromised storage nodes when they misbehave.
