Resum:
In this paper, we deal with efficient group signatures employed in secure and privacy-preserving vehicular networks. Our solution aims to minimize the impact of several common attacks like denial of services or replay attacks on the efficiency of privacy-preserving security solutions in vehicular networks. Due to advanced properties like a short-term linkability and a categorized batch verification, our solution based on group signatures ensures privacy, security and the efficiency of vehicular networks which can be attacked by malicious parties. We outline the proposed communication pattern of vehicular networks, our security solution in detail, a formal security analysis and the experimental implementation of our solution. In addition, we evaluate and compare our solution with related works. Our group signature scheme is more efficient and secure in the signing phase and in the verification phase than related schemes. © 2014, Springer Science+Business Media New York.
