It is a challenging issue to provide a secure and conditional anonymous authentication scheme in vehicle ad hoc networks(VANETs) with low storage space and computational cost. In 2008, Lu et al.  proposed an conditional privacy preservation scheme called ECPP protocol. The ECPP protocol provides conditional privacy preservation to vehicles in VANETs, that is, on one hand vehicles can achieve anonymous authentication in the network, on the other hand allow to be traced and revoked if necessary. However, ECPP scheme suffers from large storage and high computational cost. In our scheme, an improved protocol based on the concept of ECPP protocol has been proposed, which uses minimal interaction steps, little storage space and less computation overhead to achieve more efficiency conditional privacy preservation(MECPP) scheme in VANETs.
