The Latticed-Based Path Privacy Protection Aggregation Scheme for Internet of Vehicles

Abstract

With the occurrence of information leakage events of online ride-hailing, the information security of Internet of Vehicles has been highly valued by the society. Once the information of the Internet of Vehicles is exposed by the online ride-hailing platform or stolen by hackers, it will pose a fatal threat to the personal and property safety of users, and even cause a major information security accident to the whole society. Based on a post-quantum cryptography system, this paper proposes a practical privacy protection scheme for ride-hailing route information, which can present the complete statistical aggregation operation of the route and the frequency from the starting point to the destination without the visibility of the ride-hailing platform, and ensure the data privacy security of a single vehicle. Compared with representative multi-vehicle aggregation solutions, we not only guarantee message privacy, confidentiality, integrity, forward and backward security, anti-man in attack and anti-redial attack, but also achieve multi-dimensional aggregation, CCA security and anti-quantum attack. Through the analysis of the experiment, the cost of our scheme is reasonable. Therefore, the scheme is more practical in this scenario.
