Secure Range Queries in Tiered Sensor Networks

  title={Secure Range Queries in Tiered Sensor Networks},
  author={Jing Shi and Rui Zhang and Yanchao Zhang},
  journal={IEEE INFOCOM 2009},
We envision a two-tier sensor network which consists of resource-rich master nodes at the upper tier and resourcepoor sensor nodes at the lower tier. Master nodes collect data from sensor nodes and answer the queries from the network owner. The reliance on master nodes for data storage and query processing raises concerns about both data confidentiality and query-result correctness in hostile environments. In particular, a compromised master node may leak hosted sensitive data to the adversary… CONTINUE READING
