In VANETs, vehicles typically broadcast periodic beacon messages, which can be accessed by malicious attackers to track vehicles. To enhance the location privacy of vehicles and reduce the linkage between a vehicle's communication identity and its specific location, this paper proposes a location privacy protection scheme based on pseudonym exchange. By exchanging alternative pseudonyms, the anonymity entropy of vehicles is increased, thereby reducing the probability of being tracked. This approach effectively elevates the level of privacy protection for vehicles during network communications and provides a new perspective on defending against location tracking.
