The invention belongs to the technical field of Internet of Vehicles authentication security, and discloses a dynamic charging security authentication method based on chaotic mapping and a dynamic charging system. The method comprises the steps that S1, a system is initialized, and a charging provider server generates public parameters needed in the entity communication process; s2, entity initialization: initializing a fog server, a road side unit and a charging panel, and registering the fog server to a charging provider server; s3, vehicle registration: the vehicle sends the unique identity identifier to a charging provider server for registration; s4, a user logs in, and the vehicle sends a login request by inputting identity information and a password; and S5, identity authentication: blind signature of the request is realized through chaotic mapping, and mutual authentication between the vehicle and the fog server and between the vehicle and the road side unit is completed. According to the invention, the service of a VANET network is supported by centralizing communication security between cloud computing and fog computing, and the information security during vehicle authentication is ensured by an electric vehicle dynamic charging system with electric power encryption.

    本发明属于车联网认证安全技术领域,公开了基于混沌映射的动态充电安全认证方法、动态充电系统。方法包括步骤:S1.系统初始化,充电提供商服务器生成实体通信过程中所需要的公共参数;S2.实体初始化,包括对雾服务器、路侧单元、充电板进行初始化以及雾服务器向充电提供商服务器注册;S3.车辆注册,车辆将唯一身份标识发送给充电提供商服务器进行注册;S4.用户登录,车辆通过输入身份信息和密码发送登录请求;S5.身份认证,通过混沌映射实现请求的盲签名,完成车辆和雾服务器之间、车辆和路侧单元之间的相互认证。本发明通过集中于云计算和雾计算之间的通信安全以支持VANET网络的服务,以及具有电力加密的电车动态充电系统确保车辆认证时的信息安全。
