LBS provide users with relevant information based on
their location. In spite of the desirable features provided by LBS,
the geographic location of users are not adequately protected.
Location privacy is one of the major challenges in vehicular and
mobile networks. In this article, we analyse the security and
privacy requirements for LBS in vehicular and mobile networks.
Specifically, this paper covers privacy enhancing technologies
and cryptographic approaches that provide location privacy
in vehicular and mobile networks. The different approaches
proposed in literature are compared and open research areas
