摘要: 车联网的快速发展促进了电子车钥匙的研发,为解决基于智能手机的电子车钥匙与车锁之间的通信安全问题,提出了电子车钥匙场景下的安全模型和口令认证密钥交换协议。所提协议通过智能手机的协助,完成车钥匙与车锁之间的认证,即使智能手机被恶意代码侵袭或者丢失,所提协议也能保护用户的隐私。在安全模型下进行的安全性证明和性能分析表明,所提协议能够抵御字典攻击、中间人攻击、重放攻击、用户伪装攻击、内部攻击等。在计算消耗方面,所提协议性能优于同类型其他协议,减少了50.7%的计算消耗总量。

Abstract: The rapid development of Internet of vehicles has promoted the research and development of digital key. In order to solve the communication security problem between digital key and car locks, a security model and password authentication key exchange protocol are proposed. The protocol completes the authentication between the digital key and the car lock through the assistance of the smartphone. Even if the smartphone is attacked by malicious code or is lost, the protocol can protect the privacy of the user. The security proof and performance analysis of the protocol under the security model show that the protocol can resist dictionary attacks, man-in-the-middle attacks, replay attacks, malicious code attacks, disguise attacks, internal attacks, etc. The performance of this protocol in computing consumption is better than that of other protocols of the same type, reducing the total computing consumption by 50.7%.

Key words: digital key, authentication key exchange protocol, blind signature, security model, identity authentication
