Privacy Preserving Techniques for Smart Traffic

Abstract

Due to the advancement in connected car technology, the toll calculation methods have been evolved to the electronic toll collection. As the toll collection methods evolved to be electronic, they are also exposed to various attack types. The plain text toll details are communicated to the toll server through the internet, which may be a great threat to security. Various schemes are proposed for this purpose but they are not much efficient. To maintain the privacy and to collect the correct toll according to time and location, a scheme has been proposed in this thesis that is more efficient than previous schemes and uses less computation and bandwidth comparatively.
