A Traceable Concurrent Data Anonymous Transmission Scheme for Heterogeneous VANETs
Vehicular Ad Hoc Networks (VANETs) are attractive scenarios that can improve
the traffic situation and provide convenient services for drivers and
passengers via vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I)
communication. However, there are still many security challenges in the traffic
information transmission, especially in the intense traffic case. For ensuring
the privacy of users and traceability of vehicles, we propose a traceable
concurrent data anonymous transmission scheme for heterogeneous VANETs. The
scheme is based on certificateless aggregate signcryption, so it supports batch
verification. Moreover, conditional anonymity is also achieved due to the
involving of the pseudo-ID technique. Furthermore, it is a pairing-free scheme
for the merit of multi-trapdoor hash functions. As a result, the total
computation overhead is greatly reduced
