The invention discloses a vehicle anti-theft matching method and device, equipment and a medium, relates to the technical field of vehicle anti-theft, is applied to diagnosis equipment, and comprises the following steps: calculating a vehicle identification code by using a target algorithm to obtain a target mask corresponding to a security authentication algorithm, and obtaining a seed value sent by an electronic control unit; calculating the seed value and the target mask by using a security authentication algorithm to obtain a first secret key, and sending the first secret key to an electronic control unit; and obtaining a response result corresponding to the comparison result and returned by the electronic control unit after comparing the local second secret key with the first secret key, and determining whether there is permission to carry out key learning and anti-theft matching or not according to the response result. In the application, the vehicle identification code of each vehicle is different, so that the mask corresponding to the security authentication algorithm generated by each vehicle is also different, the difficulty of cracking the security authentication algorithm can be increased, and the security of the vehicle is improved.

    本申请公开了一种车辆防盗匹配方法、装置、设备及介质,涉及车辆防盗技术领域,应用于诊断设备,包括:利用目标算法对车辆识别码进行计算以得到与安全认证算法对应的目标掩码,并获取电子控制单元发送的种子值;利用安全认证算法对所述种子值和目标掩码进行计算得到第一密钥,并将第一密钥发送给电子控制单元;获取电子控制单元将本地的第二密钥和第一密钥进行比对后返回的与比对结果对应的响应结果,并根据响应结果确定当前是否有权限进行钥匙学习和防盗匹配。本申请中,由于每个车辆的车辆识别码是不一样的,所以每辆车生成的与安全认证算法对应的掩码也是不一样的,因此能够增加安全认证算法被破解的难度,提高了车辆的安全性。
