The invention discloses an automobile remote control device, and an automobile body control device, system and method. The automobile remote control device comprises a communication module running in a first execution environment and a trusted module running in a second execution environment; wherein the communication module is suitable for forwarding a received original operation instruction to the trusted module, and the trusted module is suitable for executing security operation on the original operation instruction forwarded by the communication module according to pre-stored key information to obtain a security operation instruction corresponding to the original operation instruction, and realizing remote control on an automobile according to the security operation instruction. According to the mode, the encryption and decryption operation is separated from the instruction receiving and sending operation, even if the communication module responsible for instruction receiving and sending is attacked, the safety of the trusted module cannot be affected, therefore the automobile driving safety is improved, and the attack difficulty is increased.

    本发明公开了一种汽车远程控制装置、车身控制设备、系统及控制方法,其中,汽车远程控制装置包括:运行于第一执行环境中的通信模块以及运行于第二执行环境中的可信模块;其中,所述通信模块,适于将接收到的原始操作指令转发给可信模块;所述可信模块,适于根据预先存储的密钥信息对所述通信模块转发的原始操作指令执行安全运算,得到与所述原始操作指令相对应的安全操作指令,根据所述安全操作指令实现针对汽车的远程控制。该方式使加解密操作与指令收发操作相互分离,即使负责指令收发的通信模块受到攻击,也不会影响到可信模块的安全性,从而提升了汽车行驶安全,增加了攻击难度。
