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:

To solve the problem of security and efficiency of anonymous authentication in vehicular ad hoc network,a pairing-free certificateless batch anonymous authentication scheme was proposed.The public and private keys and pseudonyms were jointly generated by the trusted third party and vehicle,so the system security didn't depend on the tamper device.The scheme can realize authentication,anonymity,traceability,unforgeability,forward or backward security,and so on.Furthermore,under the random oracle model,the scheme can resist Type I and Type II attacks.Because there is no need to use certificates during authentication,the system storage load is effectively reduced.At the same time,the scheme realizes the batch message authentication on the basis of pairing-free operation,so the authentication efficiency is improved.Therefore,the scheme has important theoretical significance and application value in the resource-limited internet of things or embedded environment.

Key words: vehicular ad hoc network, pairing-free, certificateless, anonymous authentication, random oracle model
