Abstract

Vehicular Ad-hoc Networks (VANETs) are a critical and potentially vulnerable target for attacks on both message integrity and authenticity. Existing approaches are based on computationally expensive digital signature, which also creates large message sizes due to the attachment of signatures and certificates to messages. This leads to high communication and verification overheads, both in terms of bandwidth and computational effort. In this paper we discuss an alternative approach to ensure message integrity using characteristics of the received signal for authentication and misbehavior detection.
利用VANETs中的传播效应进行身份验证和错误行为检测
车辆自组织网络(vanet)是消息完整性和真实性攻击的关键和潜在脆弱目标。现有的方法基于计算开销较大的数字签名,由于将签名和证书附加到消息中,这也会产生较大的消息大小。这将导致高通信和验证开销,无论是在带宽方面还是在计算工作量方面。在本文中,我们讨论了一种替代方法,以确保消息的完整性,利用接收信号的特征进行身份验证和错误行为检测。
