Abstract:

Vehicular Ad-hoc Networks (VANET) is an intelligent transportation system that helps people improve traffic safety and efficiency. VANET is a new type of network that provides wireless communication for mobile vehicles through dedicated short range communication (DSRC). In VANET, vehicles can communicate with other vehicles and roadside units (RSUs) that are fixed to the roadside. At the same time, the privacy issues faced by VANET cannot be ignored. VANET's features such as open access, wireless communication, and malicious node attacks may cause privacy leakage of users in VANET, which seriously affects the use of VANET. So the privacy preservation is a key topic in VANET. Many papers have summarized schemes for protecting user privacy in VANET, but most of them fail to classify privacy preservation schemes and develop a detailed criteria for evaluating these schemes. The article categorizes the privacy attacks that exist in VANET and proposes a series of evaluation criteria to enable a detailed evaluation of the performance of privacy preservation schemes.

Key words: VANET, privacy preservation, security
