| Abstract: | In this paper, focus on a two tiered sensor networks. Where resource-rich storage nodes act as an intermediate tier between sensor nodes and the sink. The storage nodes store data from their nearby sensors and process queries from the sink. In this paper, 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. To preserve privacy, SafeQ uses a novel technique to encode both data and queries such that a storage node can correctly process encoded queries over encoded data without knowing their values. To preserve integrity, we propose two schemes — one using merkle hash trees and another using a new data structure called neighborhood chains — to generate integrity verification information so that a sink can use this information to verify whether the result of a query contains exactly the data items that satisfy the query. To improve performance, we propose an optimization technique using Bloom filters to reduce the communication cost between sensors and storage nodes. |
