Instruction secure transmission method and device

According to the method and device for safely transmitting the instruction, the instruction information and the legality information are received and stored, whether the instruction information is decrypted or not is judged according to whether the legality information is legal or not, if yes, the instruction information is decrypted, and service processing is conducted according to the instruction obtained after decryption. Therefore, since the instruction information in the transmission process is obtained after the equipment end encrypts and signs the generated original instruction, the instruction information is not easy to be tampered by attacks of a man-in-the-middle, and the risk of information leakage is not easy to cause, so that the security of instruction transmission is improved, and the risk of information leakage is reduced. 本发明提供的一种指令安全传输的方法及装置，通过接收并保存指令信息和合法性信息，根据合法性信息是否合法来判断是否对指令信息进行解密，若是，则对指令信息进行解密，并根据解密后得到的指令进行业务处理。由此，由于传输过程中的指令信息由设备端对所生成的原始指令进行加密签名后得到，不容易被中间人攻击篡改指令内容，且不易造成信息泄露风险，从而提高了指令传输的
