【摘要】：由于无线网络本身的脆弱性和开放性,车载网很容易受到各种攻击和破坏,面临着信息伪造、篡改攻击与重放攻击等安全威胁。消息认证是保障车载网安全的有效技术之一,但是车载网规模较大、涉及的通信实体数量多且移动速度非常快的特点要求消息能够被快速认证。目前,b-SPECS+是公认的最好的消息批量认证的方案,具有基于软件、通信开销小、安全性高、批量认证的特点,但是该方案不能够抵制固定路边设备和车辆的合谋攻击。基于b-SPECS+提出了一个基于假名验证公钥的批量认证方案,并证明了该方案能够很好地抵制合谋攻击。性能分析结果表明,与b-SPECS+相比,所提方案不仅具有b-SPECS+的特点,而且在认证时延方面,认证的消息越多,其相对于其他方案的耗时越短。
[Abstract]:Due to the vulnerability and openness of the wireless network, the vehicle-borne network is vulnerable to various attacks and damage, facing information falsification. Tampering attack and replay attack are security threats. Message authentication is one of the effective techniques to ensure the security of vehicular network, but the scale of onboard network is large. The characteristics of the large number of communication entities involved and the very fast moving speed require that messages can be quickly authenticated. At present, b-SPECS is recognized as the best message batch authentication scheme, which is based on software. The communication cost is small, the security is high, the batch authentication characteristic. However, the scheme can not resist the collusion attacks of fixed roadside devices and vehicles. Based on b-SPECS, a batch authentication scheme based on pseudonym verification public key is proposed. The performance analysis results show that the proposed scheme not only has the characteristics of b-SPECS, but also has the characteristics of authentication delay compared with b-SPECS. The more authenticated messages are, the less time it takes to compare them to other schemes.
