Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a communication method, apparatus, and system based on device codes.
Background
The shared vehicle is a shared service which can provide vehicles driven by users in a characteristic application scene, and is a time-sharing rental mode.
With the abundance Of functions Of the terminal device, the terminal device and the shared vehicle are both provided with the bluetooth devices for transmitting control instructions, for example, unlocking Of the shared vehicle is realized, and the purpose can be achieved by only sending the string unlock to an IoT (Internet Of Things) device through the bluetooth Of the terminal device and by only sending the string lock to the IoT device to realize locking. The control instruction data is transmitted in the clear text, so that the control instruction data is easily known by others, and the others who do not pay can also obtain the authority of the shared vehicle by sending the control instruction, so that the shared vehicle can be unlocked and locked.
At present, communication data is encrypted by adopting an encryption algorithm, for example, algorithms such as AES and RSA are adopted, the encryption algorithms need to agree a secret key for encryption and decryption in advance, although data transmitted in the communication process is encrypted and cannot be decrypted, the encrypted data is also unchanged due to the unchanged control instruction, and other people can directly send the same encrypted data, so that the lock opening and closing operation can be realized. Another method for performing authentication by using dynamic passwords is, for example, setting a password for each shared vehicle, providing the password when the lock is opened and closed, and if the passwords are not correct, the corresponding operation cannot be performed. Since the password is used only once, a new password is generated again later. The password of the method is updated frequently, and the dynamic password stored in the IoT device may not be updated in time, thereby causing the lock unlocking failure.
