Description
Technical Field
The application relates to the technical field of communication in engineering machinery, in particular to an engineering machinery Bluetooth equipment identity authentication system and method.
Background
The Bluetooth communication technology is widely applied to a plurality of industries by virtue of the characteristics of low cost, low complexity and high reliability, particularly in the field of engineering machinery, can conveniently realize on-line detection and fault diagnosis, and realize wireless data acquisition and network communication, so that the adjustment and recombination of the engineering machinery working condition parameter monitoring network become very flexible and convenient. In a common bluetooth communication technology, identity authentication refers to authentication between devices, and used identity information is related information such as a bluetooth device address and a verification code, which are both in plaintext communication, and no personnel information is involved in the use of the device, so that whether a connecting party is legal or not cannot be confirmed when the bluetooth device is connected, and the risk is high in occasions with high security requirements. Moreover, when the wireless link of the Bluetooth device is established, if the current device is disconnected, other devices can still perform device authentication through the link, so that the device is easy to be utilized by illegal users, loss is caused, and a large potential safety hazard exists. Meanwhile, only plaintext communication authentication aiming at the equipment is carried out, so that all Bluetooth equipment has the same connection authority, illegal invasion is easy, and different authority management cannot be implemented by upper-layer application aiming at specific users. Therefore, in order to effectively identify legal bluetooth terminal equipment and distinguish users and authorities in the equipment authentication process, a ciphertext communication process needs to be added after a common bluetooth equipment communication link is established so as to identify whether a connecting party is legal equipment; and a user authentication process is added, and identity information of the other party user is determined before the device data of the Bluetooth is accessed, so that the connected party can confirm the identity of the connecting party, thereby carrying out authentication and management.
In the prior art, the manner of adding ciphertext communication to a communication link of a Bluetooth device is mainly as follows.
Firstly, a Bluetooth shield is issued, and user information is recorded in a server after being bound with the Bluetooth shield; and the user accesses the server according to the user information to acquire the Bluetooth address. The user equipment uses the Bluetooth address to request connection with the Bluetooth shield, and establishes a Bluetooth link with the user equipment to provide identity authentication for the user. Thereby avoiding the common potential safety hazard of the Bluetooth equipment, enhancing the trusted identity authentication of the system and improving the security of the system data. However, in the identity authentication process, after the bluetooth address is obtained according to the user information, the bluetooth shield is required to be added as a connecting device to establish a bluetooth link, and the additional device is added to increase the risk of the identity authentication system being broken, which is contrary to the original purpose of increasing the security of the system design. Meanwhile, if the Bluetooth shield is lost, an illegal user can use the Bluetooth shield to connect with the Bluetooth device, so that the Bluetooth shield has a large safety risk.
Secondly, a Bluetooth security authentication method based on a cloud computing platform by adopting a password of a handheld terminal device is adopted, and the password is set into the Bluetooth device through the handheld terminal device; and simultaneously, storing the ID password of the Bluetooth device in a server, and enabling a user to log in the server to acquire the Bluetooth device information. The Bluetooth device generates a random number as a challenge code and sends the challenge code to the handheld terminal. The hand-held terminal produces the response code according to the inquiry code, the Bluetooth device verifies the response code, and the safety identity authentication is completed after the verification is passed. However, the password is always unchanged after the setting is completed, and the password is in a fixed password mode, so that once the password is exposed, the password is very dangerous to be invaded. Moreover, the working mode of the Bluetooth device cannot be changed through the server, so that the risk of being connected by illegal devices is increased.
