论文摘要
车辆临时网络中的安全性和隐私性（VANETS）要求使用短期凭证（假名）和加密密钥对。这意味着车辆的大量计算开销，需要在短时间内经常验证许多此类化名。为了减轻甚至可以将车辆安全危险的瓶颈，我们提出了一种基于Bloom过滤器（BFS）的主动化假验证方法。我们表明，我们的计划可以通过合理的交流开销来解放其他（安全和时间至关重要的）操作的计算资源，而不会损害安全性和隐私性。
Security and privacy in Vehicular Ad-hoc Networks (VANETs) mandates use of short-lived credentials (pseudonyms) and cryptographic key pairs. This implies significant computational overhead for vehicles, needing to validate often numerous such pseudonyms within a short period. To alleviate such a bottleneck that could even place vehicle safety at risk, we propose a proactive pseudonym validation approach based on Bloom Filters (BFs). We show that our scheme could liberate computational resources for other (safety- and time-critical) operations with reasonable communication overhead without compromising security and privacy.
