在车载自组织网络中，广播信标消息是至关重要的，因为大多数安全应用都依赖于它们。然而，安全广播认证的设计面临许多安全和隐私挑战，因为车辆容易受到主动攻击和位置泄露。在本文中，我们提出了一个轻量级的认证方案，使用时间有效的流丢失容忍认证（TESLA）方案和布隆过滤器，不仅防止主动攻击，但也增加了一个隐私保护功能，使该方案具有更好的性能。仿真结果表明，该方案在验证时间和匿名性方面优于现有方案。
In Vehicular Ad hoc Networks (VANETs), broadcasted beacon messages are critical as most safety applications rely on them. However, the design of a secure broadcast authentication faces many security and privacy challenges as vehicles are vulnerable to active attacks and the revealing of location. In this paper, we propose a lightweight authentication scheme using Timed Efficient Stream Loss-Tolerant Authentication (TESLA) scheme and Bloom Filters that not only prevents active attacks but also adds a privacy-preserving feature to make the scheme have better performance. Simulation results indicate the scheme outperforms the existing schemes in terms of verification time and the level of anonymity.
