车载自组织网络（VANESTs）不断产生在附近车辆之间共享的大规模数据，以改善驾驶体验和安全性。车载通信中包含了大量的私人信息。众所周知，组密钥管理是提供安全组通信的基本密码原语。虽然已经提出了许多关于组密钥管理的方案，但它们不能很好地支持VANESTO中的安全子组和组间通信。在本文中，我们利用车辆通信的具体特点，并提出了两个组密钥分配方案提供有效的解决方案，这两个问题。我们的方案不需要用户之间的交互。存储和计算分析表明，与现有方案相比，我们的方案更高效、更通用。基于这些基本方案，我们提出了对多部群的扩展，在这种情况下，效率大大提高。我们还提供了两级多部群的扩展，这使得细粒度的真实的世界的应用程序。实验结果表明，本文提出的组密钥分配方案在安全性、计算性和通信性方面都是可行的。版权所有© 2015约翰威利父子有限公司.
Vehicular ad hoc networks (VANETs) continually produce large scale of data shared among vehicles nearby to improve driving experience and safety. The vehicular communications contain a large amount of private information. It is well known that group key management is a fundamental cryptographic primitive for providing secure group communication. Although many proposals with regard to group key management have been introduced, they cannot well support secure subgroup and intergroup communications in VANETs. In this paper, we exploit the specific features of vehicular communications and propose two group key distribution schemes providing efficient solutions to these two problems. Our schemes do not require interaction between users. Storage and computation analyses show that compared with existing schemes, our proposals are more efficient and versatile. Based on these basic schemes, we present extensions for multipartite groups, by which the efficiency is greatly improved in this scenario. We also provide the extensions for two‐level multipartite groups, which enable fine‐grained real‐world applications. The experimental results confirm that our group key distribution schemes are practical in security, computation, and communication. Copyright © 2015 John Wiley & Sons, Ltd.
