Privacy- And Integrity-Preserving Entire Range Queries In Sensor Networks
Nilesh Ashokrao Thorat · Zenodo (CERN European Organization for Nuclear Research) · 2015
The architecture of two-tiered sensor networks,whe re storage nodes serve as an intermediate tier betw een sensors and a sink for storing data and processing queries has been widely adopted because of the benefits of p ower and storage saving for sensors as well as the efficienc y of query processing. However,the importance of s torage nodes also makes them attractive to attackers. This paper we proposed Paillier Cryptosystem that prevents attackers from gaining information from both sensor collected data and sink issued queries. To preserve Privacy,A paillier cryptosystem is a modular,public key encryption sc heme,using this scheme both data and query message are encrypted such that storage node can correctly decr ypt messages of an encrypted query over encrypted d ata without knowing their value in the message. To preserve integrity,we propose two schemes�one using Merkle hash tree s and another using a new data structure called neigh borhood chains�to generate integrity verification in formation so that a sink can use this information to verify whet her the result of a query contains exactly the data items that satisfy the query. https://www.ijiert.org/paper-details?paper_id=140453
