The invention provides a cloud server, a vehicle, a mobile terminal and an authorization data updating method. The cloud server configures a key pair comprising a first key and a second key, intelligent key authorization data are generated; and digital signature is performed on the intelligent key authorization data by using the first key, the intelligent key authorization data after digital signature are sent to the vehicle through the mobile terminal; and the vehicle verifies the intelligent key authorization data after the digital signature based on the second key, updates the authorizationdata of the original intelligent key into the authorization data of the new intelligent key after the verification is passed, and cancels the authorization data of the original intelligent key or changes the authorization validity period of the original intelligent key. According to the invention, the problem that the cloud server cannot send the authorization data of the intelligent key to the vehicle terminal if the intelligent key is updated safely and dynamically under the condition that the cloud server is disconnected with the remote network of the vehicle terminal is solved.

    本发明提供一种云端服务器、交通工具、移动终端以及授权数据更新方法,云端服务器配置包括第一密钥和第二密钥的密钥对,并生成智能钥匙授权数据,以及利用所述第一密钥对所述智能钥匙授权数据进行数字签名,再将数字签名后的智能钥匙授权数据通过移动终端发送至交通工具,交通工具基于第二密钥对所述数字签名后的智能钥匙授权数据进行验证,并在验证通过后更新原有智能钥匙的授权数据为新智能钥匙的授权数据、撤销原有智能钥匙的授权数据或者更改原有智能钥匙的授权有效期。本发明解决了云端服务器在与交通工具端远程网络失联的情况下,若智能钥匙发生安全动态更新,无法将智能钥匙授权数据发送给交通工具端的问题。
