车载自组织网络（VANET）是指具备计算、感知和通信能力的车辆在一定地理区域内进行信息交换，以分发紧急信息，实现安全系统。如何对这些消息进行细粒度的控制，并确保在这样一个高度动态的环境中接收的消息来自声称的源仍然是影响服务质量的关键挑战。在本文中，我们提出了一个分层的访问控制与认证方案传输的消息与VANET的安全保证。通过扩展密文策略基于属性的加密（CP-ABE）与多个权威的层次结构，该方案不仅实现了可扩展性，由于其层次结构，但也继承了细粒度的访问控制的消息传输。该方案还利用基于属性的签名（ABS），可以授权的车辆，可以最适当地处理有效的消息。效率分析和与相关工作的比较结果表明，该方案是有效的和可扩展的，在处理访问控制和消息认证的数据分发在VANET。(C)2014爱思唯尔有限公司版权所有。
In vehicular ad hoc network (VANET), vehicles equipped with computing, sensing, and communication capabilities can exchange information within a geographical area to distribute emergency messages and achieve safety system. Then how to enforce fine grained control of these messages and ensure the receiving messages coming from the claimed source in such a highly dynamic environments remains a key challenge that affects the quality of service. In this paper, we propose a hierarchical access control with authentication scheme for transmitted messages with security assurance over VANET. By extending ciphertext-policy attribute-based encryption (CP-ABE) with a hierarchical structure of multiple authorities, the scheme not only achieves scalability due to its hierarchical structure, but also inherits fine-grained access control on the transmitted messages. Also by exploiting attribute-based signature (ABS), the scheme can authorize the vehicles that can most appropriately deal with the message efficiently. The results of efficiency analysis and comparison with the related works show that the proposed scheme is efficient and scalable in dealing with access control and message authentication for data dissemination in VANET.
