Identity-based internet of Vehicles privacy security protection method

Abstract

The invention belongs to the field of mobile communication, and discloses an identity-based Internet of Vehicles privacy security protection method, which comprises the following steps: (1) after a system is initialized, enabling a roadside unit infrastructure (RSU) to register to a certificate authority / trusted center (CA), and enabling the CA to generate a certificate for the RSU; (2) generatinga pseudo identity by an on board unit (OBU); (3) when the OBU enters the RSU coverage area of the roadside unit, performing bidirectional verification on the RSU and the OBU through different algorithms; (4) enabling the CA to process and broadcast the verification result. According to the method disclosed in the invention, scheme design is carried out by combining an elliptic curve algorithm with a bilinear pair mapping theory, the unique advantages of the RSU are utilized, and the main information of the system is stored in the RSU; different algorithm bidirectional authentication between the RSU and the OBU is carried out by using a shared key, an identity ID and a handshake principle in a communication process; therefore the security and efficiency of identity authentication are improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for protecting privacy and security of Internet of Vehicles based on two-way authentication of identity. Background technique [0002] The Internet of Vehicles (IOV) is a vital part of the intelligent transportation system. It is a spontaneously created network form, mainly used for data exchange. It is composed of entities on the road connected to each other to sense traffic conditions and supervise The running status of the car can effectively improve the road traffic. The architecture of the vehicle network is as follows figure 1 shown. The Internet of Vehicles can provide a variety of intelligent service models for smart transportation, integrating technologies such as the Internet of Things, traditional Internet, and mobile Internet, but it also creates more complex security issues. Due to the high mobility of vehicle nodes, attackers can access, threaten and d...

AI Technical Summary

Problems solved by technology

The amount of calculation and storage of OBU in the RSU-based scheme is much smaller than other schemes, but the signature and verification signature in this scheme largely depend on RSU, so V2V communication is not supported, and all communication depends on RSU

The authentication scheme based on group signature reduces the requirement for OBU storage capacity, but introduces the role of group administrator, if this role is attacked, it will cause a serious blow to the network
