基于区块链的车联网安全技术应用研究

Research on the Applicationof Internet of Vehicles Security Technology Based on Blockchain

车联网的快速发展带来了诸多安全挑战,亟需一种安全可信的网络架构。针对车联网面临的身份认证、数据保护、隐私保护等安全威胁,提出了一种基于区块链的多层级车联网安全防护体系。该体系采用区块链技术构建安全可信的网络环境,利用智能合约实现车辆权限管理,并通过同态加密、环签名等密码学机制保护车辆隐私。系统仿真实验表明,所提安全方案能有效抵御多种安全攻击、保障车联网的可靠运行,为车联网安全领域提供了新的思路和方法。

The rapid development of the Internet of Vehicles has brought many security challenges,and there is an urgent need for a secure and trustworthy network architecture.This paper proposes a multi-level blockchain based security protection system for the Internet of Vehicles,addressing security threats such as identity authentication,data protection,and privacy protection.This system uses blockchain technology to build a secure and trustworthy network environment,utilizes smart contracts to manage vehicle permissions,and protects vehicle privacy through cryptographic mechanisms such as homomorphic encryption and ring signatures.The system simulation experiment shows that the proposed security scheme can effectively resist various security attacks,ensure the reliable operation of the Internet of Vehicles,and provide new ideas and methods for the field of Internet of Vehicles security.
