Abstract

In 2013, Shim proposed a conditional privacy-preserving authentication (CPP-BAT) scheme for vehicular ad hoc networks (VANETs). Their scheme was designed to improve Jiang et al.'s binary authentication tree (BAT) scheme that claimed insecure against forgery attacks, replay attacks, and Sybil attacks. Unfortunately, we also found out that Shim's CPP-BAT is potentially insecure against non-repudiation attacks. In this short article, we address the issue and give our improvement to withstand the threat.
VANETs中pcp - bat的光重建
2013年,Shim提出了一种针对车辆自组织网络(VANETs)的条件隐私保护认证(pcp - bat)方案。他们的方案旨在改进Jiang等人的二进制认证树(BAT)方案,该方案声称对伪造攻击、重放攻击和Sybil攻击不安全。不幸的是,我们还发现Shim的pcp - bat对于不可否认攻击是潜在的不安全的。在这篇简短的文章中,我们解决了这个问题,并给出了我们的改进来抵御威胁。
