The invention discloses a vehicle charging authentication method and device, a vehicle and a charging pile, and relates to the technical field of vehicles, the technical scheme comprises the following steps: receiving charging pile authentication information, a charging pile serial number and charging code signature information, the charging code signature information is obtained by using the charging pile signature information to sign a charging code, obtaining a random number in broadcast information according to a binding relationship between vehicle identification information and a charging pile serial number, generating a first encryption key according to the random number and the charging pile authentication information, encrypting the charging code signature information by using the first encryption key, and sending the encrypted charging code signature information to a server; and the encrypted charging code signature information is sent to the charging pile, so that the charging pile authenticates the encrypted charging code signature information. And the vehicle receives the broadcast as a main device, and executes a dual authentication mode of authentication and signature based on the charging pile authentication information, the charging pile serial number and the charging code signature information, so that the safety of charging authentication is improved.

    本公开公开了车辆充电的认证方法及装置、车辆、充电桩,涉及车辆技术领域,技术方案包括:接收充电桩认证信息、充电桩序列号、充电码签名信息,所述充电码签名信息使用充电桩签名信息对充电码进行签名得到,根据绑定关系获取广播信息中的随机数,所述绑定关系为车辆标识信息与充电桩序列号的绑定关系,根据所述随机数及所述充电桩认证信息生成第一加密密钥,使用所述第一加密密钥对所述充电码签名信息进行加密,并将加密后的充电码签名信息发送至充电桩,以便充电桩对所述加密后的充电码签名信息进行认证。车辆作为主设备接收广播,并基于充电桩认证信息、充电桩序列号,充电码签名信息执行认证和签名的双重认证方式,增加充电认证的安全性。
