Proxy signature-based RSU message broadcasting in VANETs

We propose a framework for a secure RSU-to-OBU message broadcasting in VANETs using proxy signatures. We consider a VANET infrastructure for which the network assumptions are similar to the current standards of VANET communications. The main purpose of our scheme is to provide message integrity, authenticate the broadcast messages, and authenticate the RSU to the OBUs. We set the appropriate liabilities to the network components enabling the OBU to verify the received message for its validity
