With an increasing number of cloud service
providers (CSPs), research works on multi-cloud environments
to provide solutions to avoid vendor lock-in and deal with
the single-point failure problem have expanded considerably.
However, a few schemes focus on the conditional privacy protection authentication of vehicular networks under a multi-cloud
environment. In this regard, we propose a robust and extensible
authentication scheme for vehicular networks to fulfil the evergrowing diversified service demands from users. According to our
solution, the vehicles need to register with the trusted authority
(TA) only once to achieve a fast and efficient authentication
with CSPs. Additionally, as long as the new CSP is successfully
registered in TA, it can participate in vehicular service. A cloud
broker, which is managed by the TA, is responsible for connecting
all the cloud services; consequently, the complexity involved in
the selection of CSPs is hidden from the users’ view. A detailed
security analysis establishes that our scheme can fulfil conditional
privacy protection and achieve the security objectives of vehicular
networks. Our scheme is based on elliptic curve cryptography
and does not employ the complex bilinear pairing operation. An
evaluation of performance of the proposed scheme indicates that
it is suitable for applications involving vehicular networks.
