在这篇文章中，我们讨论了在安全和隐私保护的车载网络中使用的高效群签名。我们的解决方案旨在将拒绝服务或重放攻击等几种常见攻击对车载网络中保护隐私的安全解决方案的效率的影响降至最低。由于具有短期可链接性和分类批量验证等先进特性，基于群签名的解决方案确保了车载网络的隐私性、安全性和效率，使其能够受到恶意方的攻击。我们概述了车载网络的通信模式，详细介绍了我们的安全解决方案，并对我们的解决方案进行了形式化的安全分析和实验实现。此外，我们对我们的解决方案进行了评估，并与相关工作进行了比较。在签名阶段和验证阶段，我们的群签名方案比相关方案更高效、更安全。
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.
