Abstract

Recently, Lu . proposed an efficient conditional privacy preservation protocol, named ECPP, based on group signature scheme for secure vehicular communications. However, ECPP dose not provide unlinkability and traceability when multiple RSUs are compromised. In this paper, we make up for the limitations and propose a robust conditional privacy-preserving authentication protocol without loss of efficiency as compared with ECPP. Furthermore, in our protocol, RSUs can issue multiple anonymous certificates to an OBU to alleviate system overheads for validity check of RSUs. In order to achieve these goals, we consider a universal re-encryption scheme as our building block.
