Abstract

Abstract: Abstract: To address the issues in cross-domain authentication for the VANETs, including the inability to distinguish vehicle types, excessive overhead caused by repeated authentication, and insufficient security, a Cross-domain Handover Authentication Scheme with Vehicle Type Verification (CHAS-VTV) is proposed. CHAS-VTV employs certificateless public key cryptography to eliminate key escrow and certificate management problems while improving cross-domain authentication efficiency. A dynamic accumulator is utilized to store and verify vehicle types, which enables classified cross-domain identity authentication. Considering the complete process of cross-domain vehicle movement, Hash-based Message Authentication Code (HMAC) is adopted to achieve efficient handover authentication between vehicles and multiple RSUs. Security analysis demonstrates that CHAS-VTV resists various malicious attacks, including public key replacement attack, private key leakage attack, and forgery attack. Performance evaluations indicate that compared to existing cross-domain handover authentication schemes, CHAS-VTV reduces computational overhead by over 78.81% and 77.76% in the cross-domain authentication and handover authentication phases while lowering communication overhead by more than 65.29% and 30.08%.

摘要： 针对车联网跨域认证中无法区分车辆类型、重复认证、安全性不足等问题，提出了一种支持车辆类型验证的车联网跨域切换认证方案CHAS-VTV。基于无证书公钥密码体系设计了一种无证书跨域认证机制，解决密钥托管和证书管理问题并提高车辆跨域认证效率；基于动态累加器设计了一种车辆类型存储和验证机制，实现车辆分类型跨域认证；采用基于哈希的消息验证码设计了一种切换认证机制，实现车辆与多个路边单元的高效切换认证和密钥协商。安全性分析表明，CHAS-VTV能够有效抵抗公钥替换攻击、私钥泄露攻击、伪造攻击等多种恶意攻击。性能分析表明，CHAS-VTV与现有跨域切换认证方案相比，在跨域认证和切换认证中计算开销最高降低了78.81%和77.66%，通信开销最高降低了65.29%和30.08%。
