摘要:

目前主流的车-云安全通信方法是采用公钥保护对称密钥加密数据,但公钥方法计算耗时,且存在被以量子计算为代表的超计算能力快速破解的风险。因此,当前智能网联汽车车-云通信存在着较大的安全隐患。本文将量子密钥应用于对称密钥的保护,提出了一种全新的融合量子密钥的车-云加密通信架构,实现了通过预置密钥进行对称会话密钥的无线分发和BB84协议下对称会话密钥的实时协商。对上述架构进行安全性分析和性能分析,结果表明该架构在威胁场景下对数据具有较高的保护性,通信的平均时延和丢包率控制在16.861 ms和0.0248%范围内,实现了安全高效的车-云通信。

Abstract:

At present, the mainstream vehicle-cloud secure communication method uses public key to protect symmetric key to encrypt data, but the public key method is time-consuming and there is the risk of being quickly cracked by supercomputing power represented by quantum computing. Therefore, the current intelligent networked vehicle-cloud communication has great security risk. In this paper, quantum keys are applied to the protection of symmetric keys, and a new vehicle-cloud encryption communication architecture based on quantum keys is proposed, which realizes wireless distribution of symmetric session keys through preset keys and real-time negotiation of symmetric session keys under the BB84 protocol. The security analysis and performance analysis of the above-mentioned architecture show that the architecture has high protection for data in threat scenarios, with the average communication delay and packet loss rate controlled within the range of 16.861 ms and 0.0248%, thus achieving safe and efficient vehicle-cloud communication.
