EPCT: An Efficient Privacy-Preserving and Collusion-Resisting Top-k Query Processing in WSNs

Data privacy threat arises during providing top-k query processing in the wireless sensor networks. This article presents an efficient privacy-preserving and collusion-resisting top-k(EPCT) query processing protocol. A minimized candidate encrypted dataset determination model is first designed, whic...
