Abstract

Abstract:

A great challenge to wireless sensor networks（WSN）is how to protect privacy from disclosing during application in WSN as well as obtain accurate results.In recent years,researchers at home and abroad have done much work on privacy-preserving in WSN.This paper surveys the general privacy-preserving methods from two aspects of location privacy and data privacy in WSN and analyzes their theories and characteristics.A new method based on multi-notes phantom routing protocols and ECC homomorphic encryption is proposed in this paper,which can protect location privacy and data privacy at the same time.Compared to current methods,better privacy will be protected and less energy will be consumed.

Key words: wireless sensor networks（WSN）, privacy preservation, phantom routing, ECC homomorphic encryption
