In recent years, more and more research has been focusing on trust management of Vehicle Ad-hoc NETworks (VANETs) for improving the safeguard of vehicles. However, in these researches, little awareness has been rewarded to the location privacy due to the natural conflict between trust and anonymity, which is the basic safeguard of privacy. Although traffic safety remains the most crucial problem in VANETs, location privacy can be just as important for driver, and neither can be ignored. In this paper, the authors suggest a signal-based trust management method that aims to censor internal attacker from transfer false messages in privacy-improved VANETs.
