摘要
[目的/意义]基于身份的车载自组网认证方案在提升交通安全性和数据安全性,改善交通效率,推动智能交通发展等方面,具有重要的价值意义.[方法/过程]分析一种基于身份的车载自组网的认证方案,发现在身份匿名认证过程中的签名阶段,存在着伪造攻击的风险.通过对签名方案实施伪造攻击且伪造结果能被接受,证明了方案存在着被攻击的潜在风险.[结果/结论]以一种新的解决方案,在原签名方案基础上,得到了新的车载网认证方案.相比原方案,新方案有效地解决了伪造攻击的问题,且提高了签名的时间和效率,进一步保护了用户的隐私安全.
Abstract
[Purpose/Significance]The identity-based vehicular ad hoc network authentication scheme has significant value in enhancing traffic safety,data security,improving traffic efficiency,and driving intelligent transportation development.[Method/Process]This article analyzes an identity-based vehicle network authentication scheme and finds that there is a risk of forgery attack in the signature stage of the identity-based anonymous authentication process.This article implemented forgery attacks on this signature scheme and the forgery results were acceptable,demonstrating the potential risk of being attacked by this scheme.[Results/Conclusion]This article proposes a new solution,which utilizes the idea of certificateless signature and derives a new vehicle network authentication scheme based on this signature scheme.Compared to the original scheme,the new scheme effectively addresses the issue of forgery attacks,improves the time efficiency of signing,and further protects user privacy and security.
