Detecting Malicious Storage Node in WSN
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 10
Abstract
The architecture of two-tiered sensor networks where the storage nodes serve as an intermediate tier between sensors and a sink for storing data and processing queries has been widelyadopted because of the benefits of power and storage saving for sensors as well as the efficiency of query processing. The importance of storage nodes also makes them attractive to attackers. The SafeQ a protocol that prevents attackers from gaining information from both sensor collected data and sink issue queries. SafeQ also allows a sink to detect compromise storage nodes. To preserve privacy SafeQ use a novel techniques to encode both data and queries such that a storage node can correctly process encoded queries over encoded data without knowing their values. The preserve integrity have two schemes one using Merkle hash trees and another using a new data structure called neighborhood chains to generate integrity verification information.
