LBS-based anti-attack location privacy protection method for IoV

Abstract

The invention discloses an LBS (Location Based Service) anti-attack location privacy protection method for IoV (Internet of Vehicles). The method specifically includes five steps of grouping encryption and decryption; message content comparison; service provider signing; result set screening by a trusted third party; feedback of service content to an applicant. According to the invention, the whole communication process is divided into two parts generally: a user requests service from a service provider; and the service provider returns the service content. Discrete logarithm and the Diffie-Hellman are adopted in the above model, bidirectional authentication is supported and save cost and computation cost are reduced substantially. Therefore, privacy protection and service quality are balanced effectively and different types of attacks can be resisted.

Description

technical field [0001] The invention relates to the Internet of Vehicles technology, in particular to an anti-attack based location privacy protection method in the Internet of Vehicles under the background of LBS. Background technique [0002] The Internet of Vehicles is based on the multi-network integration of the intra-vehicle network, the Internet of Vehicles and the vehicle-mounted mobile Internet. "Safety, entertainment, and energy saving" are the main goals. It brings together related technologies such as sensors, RFID, data mining, and automatic control. The standard is to realize the mutual integration of car-X (X: car, road, pedestrian, Internet). While advanced in-vehicle networking technology brings various service experiences to users, due to the characteristics of network self-organization and no center, it faces more serious security threats than ordinary mobile networks. [0003] In the Internet of Vehicles system, location-based service (LBS) applications ...

AI Technical Summary

Problems solved by technology

However, the protocol also has certain challenges: (1) Each vehicle must have enough storage space to save public-private key pairs and corresponding certificates

(2) Authorities also need a very large storage space to store vehicle certificates

(3) If it is completely anonymous, when the attacker sends an error message, it is difficult for the authority to find his real identity from all the certificates

However, Zhang's scheme is vulnerable to impersonation attacks and anti-tracking attacks

[0007] To sum up, the existing technical solutions have more or less certain defects and cannot comprehensively meet the corresponding needs
