Abstract

With the popularity of the Internet of Vehicles (IoV), a large amount of data is being generated every day. How to securely share data between the IoV operator and various value-added service providers becomes one of the critical issues. Due to its flexible and efficient fine-grained access control feature, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is suitable for data sharing in IoV. However, there are many flaws in most existing CP-ABE schemes, such as attribute privacy leakage and key misuse. This paper proposes a Traceable and Revocable CP-ABE-based Data Sharing with Partially hidden policy for IoV (TRE-DSP). A partially hidden access structure is adopted to hide sensitive user attribute values, and attribute categories are sent along with the ciphertext to effectively avoid privacy exposure. In addition, key tracking and malicious user revocation are introduced with broadcast encryption to prevent key misuse. Since the main computation task is outsourced to the cloud, the burden of the user side is relatively low. Analysis of security and performance demonstrates that TRE-DSP is more secure and practical for data sharing in IoV.

TRE-DSP：基于CP-ABE的可追溯和可撤销的物联网数据共享方案，具有部分隐藏策略

随着车联网（IoV）的普及，每天都会产生大量的数据。如何在车联网运营商和各种增值服务提供商之间安全地共享数据成为关键问题之一。密码策略属性加密（cipher - policy Attribute-Based Encryption, CP-ABE）具有灵活高效的细粒度访问控制特性，适用于车联网中的数据共享。然而，现有的大多数CP-ABE方案存在属性隐私泄露和密钥滥用等缺陷。提出了一种可追溯、可撤销、部分隐藏策略的基于cp - abe的车联网数据共享方案。采用部分隐藏的访问结构隐藏敏感的用户属性值，属性分类随密文发送，有效避免隐私暴露。此外，通过广播加密引入密钥跟踪和恶意用户撤销，防止密钥误用。由于主要的计算任务外包给了云，用户端的负担相对较低。安全性和性能分析表明，TRE-DSP在车联网数据共享中更加安全实用。
