【摘要】：针对当前车联网中匿名认证的安全性与效率问题,提出一种基于非线性对的车联网无证书批量匿名认证方案。通过可信中心与车辆协同生成公私钥对和假名,摆脱了系统安全对防篡改装置的依赖。分析表明,该方案能够实现可认证性、匿名性、可追踪性、不可链接性、前向与后向安全性等多种安全性能,并在随机预言模型下证实了该方案能够抵抗Type I与Type II攻击;该方案采用无证书的认证方式,有效减轻了系统存储负载,同时方案在非线性对运算基础上,实现消息的批量认证,有效提高了认证效率。因此,该方案在资源受限的物联网或嵌入式环境中,有着重要的理论意义与应用价值。
[Abstract]:Aiming at the security and efficiency of anonymous authentication in vehicle networking, this paper proposes an anonymous authentication scheme based on nonlinear pairs, in which public and private key pairs and pseudonyms are generated by means of trusted centers and vehicles. The analysis shows that the scheme can achieve many kinds of security performance, such as authentication, anonymity, traceability, non-link, forward and backward security and so on. It is proved that the proposed scheme can resist Type I and Type II attacks under the stochastic prediction model. This scheme adopts the authentication method without certificate, effectively reduces the storage load of the system, and realizes the batch authentication of messages on the basis of nonlinear pair operation, which effectively improves the efficiency of authentication. This scheme has important theoretical significance and application value in the resource constrained Internet of things or embedded environment.
