- W4297980384 abstract "Abstract With the rapid development of the Internet of Things and the continuous progress of 5G technology, intelligent transportation has become the development trend of transportation technology. As an information interaction network, the Internet of Vehicles can share traffic information among vehicles, bringing convenience to vehicle owners while improving traffic efficiency.Data forwarding technology in the Internet of Vehicles (IoV) can realize the safe and efficient forwarding of messages, so that vehicle users can obtain road information as soon as possible and take relevant measures in advance.Cybertwin, as a complete replica of the vehicle in the virtual world, masters all the data and behavior of its physical vehicle. Cybertwin can communicate with other vehicle’s Cybertwin in the virtual world, which provides powerful functions in the data forwarding. On the one hand, it can directly forward data on behalf of the physical vehicle; on the other hand, Cybertwin can make relevant decisions based on forwarded data from other twins. However, it is easy to be eavesdropped when forwarding its physical vehicle data. In addition, there are several Cybertwins that may refuse to forward data in the virtual world. Therefore, the security issues in the data forwarding of Cybertwin face many challenges. In this paper, data aggregation and cluster-head multi-hop transmission scheme based on Cybertwin is proposed. The proposed scheme uses the reversible matrix to construct the data forwarding report of different cyber twins, uses the Paillier cryptosystem to aggregate the ciphertext of the data report, and uses the reversible matrix to decrypt and restore. In addition, use randomizable signatures to protect the privacy of Cybertwin. The security analysis results show that the proposed scheme can effectively improve the efficiency of data forwarding, and better protect the privacy and security issues of Cybertwin data forwarding in the IoV." @default.
