摘要: 车联网在智能交通系统构建中发挥重要作用,消息认证方案能够为车联网的实际应用提供可靠性和安全性保障,但现有认证方案多数存在计算效率低下的问题,为此,提出一种基于切比雪夫混沌映射的车联网认证方案。利用切比雪夫多项式的半群性质构建对称密钥,以实现车辆节点与路边设施单元(RSU)的密钥协商。车辆节点使用由RSU分发的时效性共享密钥完成车辆间的匿名消息认证,无须为每个消息签名验证一个较大的撤销列表,车辆的撤销也不会影响群组性能。分析结果表明,该方案可以满足车联网的安全需求并抵御多种安全攻击,同时提供条件隐私保护,其密钥协商与消息认证阶段的计算效率较高,通信开销较低。

Abstract: Vehicular Ad-hoc Network(VANET) plays an important role in the construction of intelligent transportation systems.The message authentication schemes can ensure the reliability and security of VANET in practical applications, but most of the existing authentication schemes are limited in the computational efficiency.To address the problem, an authentication scheme based on Chebyshev chaotic map for VANET is proposed.With the semi-group nature of Chebyshev polynomial, the proposed scheme securely constructs the symmetric key to finish the key agreement phase between vehicle nodes and the Road-Side Unit(RSU).Then the vehicle nodes use the temporary shared key distributed by RSU to complete the anonymous message authentication phase.There is no need to verify a large revocation list for each signature, and the revocation of vehicles will not affect the performance of the group.The analysis results show that the proposed scheme satisfies the security requirements of VANET for resisting a variety of security attacks, and provides conditional privacy-preserving at the same time.In the key agreement phase and message authentication phase, the scheme exhibits an improved computational effiency and reduced communication overhead.
