Title:
INTERMITTENT COOPERATIVE INTERFERENCE-BASED ANTI-EAVESDROPPING METHOD FOR INTERNET OF VEHICLES
Document Type and Number:
WIPO Patent Application WO/2021/068369
Kind Code:
A1
Abstract:
Disclosed is an intermittent cooperative interference-based anti-eavesdropping method for the Internet of Vehicles. The method comprises: first, under the premise of effectively preventing illegal users Ve from eavesdropping on information, establishing an optimization problem by using minimizing the energy consumption of cooperative interference users Vj as a goal; then, on the basis of a WAVE protocol, analyzing unique communication characteristics of the Internet of Vehicles, obtaining the time structure of physical layer data packets of the Internet of Vehicles as well as the duration of the physical layer data packets, and solving for the shortest duration of the physical layer data packets in the Internet of Vehicles; next, solving an optimal cooperative interference scheme for any available power range of the cooperative interference users Vj; and finally, sequentially periodically cycling the cooperative interference users Vj during a legal user data transmission period according to the solved optimal cooperative interference scheme until transmission by legal users ends. The present invention may enable cooperative interference users to use minimal energy consumption to prevent illegal users from eavesdropping on communication information of the Internet of Vehicles.
