Remote Identity Authentication in Heterogeneous Vehicle Environment Based on the Trusted Computing

In this paper, a solution with attribute encryption and signature is proposed, at the point that the existing identity encryption mechanism is just related to someone's identity in the vehicular cloud and will lead to privacy leak problem. Therefore, when the encryption mechanism based on operator attributes is built, the signature schemes should be introduced. The application of the attribute encryption and signature solution is in the access architecture of the Trusted Vehicular Cloud (TVC). The research is not only to divide the fine-grained and dynamic property of the access permissions but also to resist collusion attack. This solution is with confidentiality, authentication and non-repudiation. A set of credible support mechanism are constructed for TVC platform, which are used for the unified management of the Vehicular Cloud Computing (VCC) platform. The establishment of the management mechanism is first to make clear the roles and the relationships of different users on the VCC platform. Then the trusted ecosystem which is participated by multiple users is set up. This solution considering the VCC environment is more practical because the safety problem is return to the nature of building the architecture of the system.
