Abstract:
To solve the problem that the existing TTP-free protocols cannot resist attacks from multiple dishonest users colluding with a location-based services(LBS)provider(P)efficiently,a location privacy-preserving protocol based on secure multi-party sum(SMS)and verifiable secret sharing(VSS)is proposed.SMS is used to compute the centroid sent to P as a cloaking location and VSS is used to encrypt the location,and location privacy-preserving is realized and the correctness of the cooperative user data is verified.Experiments show that the protocol can resist the passive and active attacks from insiders and outsiders and detect dishonest cooperative users efficiently,and it can provide strong location privacy-preserving for LBS.
