Secure and privacy-preserving broadcast authentication for IVC

Vehicle-to-Vehicle(V2V) communication is a part of the future vehicular network. As the location information of vehicles is broadcasted frequently, there is a demand on privacy protection on this information. In this thesis we defined the requirements on privacy-protection broadcast authentication schemes for V2V communication. We analyzed the existing authentication schemes according to the requirements. But the major contribution of this thesis is that we devised an authentication scheme CLIBA on the messages of vehicles, which is based on the CL-Idemix protocol suite. The scheme realizes attribute authentication to prevent privacy leakage of vehicles. We also evaluated CLIBA according to the requirements. It shows that CLIBA fulfills most of the requirements except that the performance is not quite satisfactory compared to the strict efficiency requirement of V2V communication
