The emerging Vehicular Ad hoc NETworks (VANETs) can improve safety, efficiency and convenience in transportation. In spite of the expected benefits, VANETs also introduce some location privacy risk by periodically broadcasting vehicular information. Pseudonym change is commonly accepted as one approach to protect location privacy in VANETs, but the effectiveness of most pseudonym change schemes has...
Changing pseudonyms are commonly accepted as one approach to protect location privacy in VANETs, but the effectiveness of most changing pseudonyms schemes have never been investigated rigorously. In this paper, we present a detailed analytical model based on a kind of simplest scheme, called Random Changing Pseudonyms (RCP), to quantify the level of location privacy provided by this scheme. Furthermore,...
