笔记
In vehicular ad hoc networks (VANETs), the broadcasting of fake announcement messages by malicious vehicles can potentially misguide nearby vehicles. Ensuring the trustworthiness of announcement messages while preserving the privacy of vehicles is a significant challenge in the design of an announcement scheme for VANETs. To address this challenge, we propose a privacy-preserving announcement scheme with strong trustworthiness based on a new security tool called message linkable group signature with information binding and efficient revocation. Compared with the existing privacy-preserving announcement schemes, our proposed scheme not only achieves the traditional trustworthiness requirement of an announcement message but also provides strong trustworthiness, which makes it resistant to sybil and collusive attacks. To the best of our knowledge, our scheme realizes strong trustworthiness for the first time. Simulations were also performed to show the practicability of the scheme.
在车载自组网(VANETs)中，恶意车辆广播虚假公告消息可能会误导附近的车辆。在设计VANETs的公告方案时，确保公告消息的可信度同时保护车辆隐私是一个重要挑战。为了应对这一挑战，我们提出了一个基于新型安全工具的具有强可信度的隐私保护公告方案，该工具被称为具有信息绑定和高效撤销功能的消息可链接群签名(message linkable group signature with information binding and efficient revocation)。与现有的隐私保护公告方案相比，我们提出的方案不仅实现了公告消息的传统可信度要求，还提供了强可信度，使其能够抵抗女巫攻击(sybil attack)和共谋攻击(collusive attack)。据我们所知，我们的方案首次实现了强可信度。我们还进行了仿真实验来展示该方案的可行性。
