ESPQuery: An Enhanced Secure Scheme for Privacy-Preserving Query based on Untrusted Devices in the Internet of Things

The development of the Internet of Things (IoT) has brought various IoT services, which facilitate and enrich human life. All these services are at risk of privacy leakage. The privacy-preserving issue of IoT query, which is a typical service, has attracted much attention. A superior candidate for solving the above issue is classical cryptographic schemes based on the computational difficulty. Wit...
