The registration security credential of the device refers to an asymmetric key used for registering the device in the central service system and used for generating an authentication signature.
How the security credentials of the edge IoT devices are securely stored is one of the keys to protect the business interests of the company. In the related art, the registered security credentials are typically stored in a memory of the device, which may cause an uncontrolled registration of the security credentials if the device is uncontrolled or lost.

The present disclosure is not limited to a particular class of terminal devices.
In a possible implementation manner, when the terminal device leaves a factory, the registration security credential of the terminal device may be written into a preset field of the license authorization file, and the license authorization file is encrypted by the encryption key to obtain the license authorization file in a ciphertext form.
Wherein, the encrypted license authorization file can be packaged with the software program of the device and stored in the memory (such as a disk) of the terminal device; and, the encryption key of the license authority file is stored in the encryption chip of the device.
Therefore, the encrypted license file is stored in the memory of the terminal device, the license file comprises the registration security certificate of the terminal device, the encryption chip of the terminal device stores the encryption key of the license file, and the security is high.
After the terminal device is deployed to a corresponding location or place, when the terminal device is started, the terminal device may connect with a server (e.g., a central server, a cloud server, etc.) through a public network and register with the server, so that the server may confirm the legal identity of the terminal device.
In one possible implementation manner, in step S11, the encryption key of the license authorization file may be obtained from an encryption chip of the terminal device. The security interface of the encryption chip can be called to read the license authorization file encryption key from the encryption chip.
In one possible implementation manner, in step S12, the license authority file in the memory may be decrypted by the encryption key, so as to obtain the decrypted license authority file.
In one possible implementation manner, in step S13, the registration security credential may be obtained according to the decrypted license authorization file. The decrypted license authorization file can be analyzed to obtain the file content of the decrypted license authorization file; and determining the preset field of the file content as a registration security certificate.
In one possible implementation, in step S14, an authentication signature may be generated according to the acquired registration security credential. The present disclosure does not limit the manner in which the authentication signature is generated.

and storing the encryption key into the encryption chip.
That is, the terminal device may have an initial license authorization file for authorizing the terminal device's local system to use various functions of the device itself (e.g., various applications). If the registered security certificate is directly stored in the encryption chip, the capacity of the encryption chip may be exceeded, and meanwhile, the factory configuration process is greatly changed, so that the complexity of the factory configuration process can be improved.
In this case, the registration security credential of the terminal device may be written into a preset field of the initial license authorization file; and then, the encrypted license authorization file is obtained by encrypting through the encryption key of the license authorization file.
In a possible implementation manner, the encrypted license authorization file may be directly stored in a memory (e.g. a disk) of the terminal device, or the encrypted license authorization file may be packaged with a software program of the device and stored in the memory of the terminal device, and the encryption key is burned into an encryption chip of the terminal device, so as to implement the combination and encrypted storage of the registration security credential and the license authorization file.
By the method, the safety of the registered safety certificate can be improved, the safety risk when the equipment is out of control is reduced, and the influence on the factory configuration process is small.
After the terminal device is deployed to a corresponding position or place, the terminal device can be connected with the server through the public network and registered with the server under the conditions of starting, restarting or disconnecting the network and reconnecting the terminal device and the like. Step S11-step S14 may be a registration preparation phase.
In one possible implementation, step S11 may include: and calling a security interface of the encryption chip, and reading the encryption key from the encryption chip.

In one possible implementation, step S13 may include:
analyzing the decrypted license authorization file to obtain the file content of the decrypted license authorization file; and determining the registration security certificate according to the preset field of the file content.
That is, the decrypted license file may be analyzed to obtain the file content of the decrypted license file, and the analysis manner of the license file is not limited in the present disclosure.
In one possible implementation manner, according to the file content of the license authorization file, the content of a preset field (e.g. 128-th and 256-th bits) of the file content can be read and determined as the registration security credential.
In this manner, the registration security credentials may be obtained from the license authorization file.
Further, in step S14, an authentication signature may be generated from the acquired registration security credential so that registration may be performed based on the authentication signature. The present disclosure does not limit the manner in which the authentication signature is generated.
Fig. 2 shows a schematic diagram of a registration preparation phase of a device registration method according to an embodiment of the present disclosure. As shown in fig. 2, the steps of the registration preparation phase may be performed at device start-up.

in step 2-3, a registration security certificate for equipment access can be acquired through a preset field of the license authorization file;
in step 2-4, an authentication signature may be generated based on the registered security credentials. Further, a device registration procedure may be initiated.
In one possible implementation, an agent process is run in the terminal device for connecting to the server. In the device registration phase of step S15-step S16, the terminal device may perform registration through a proxy process.
In one possible implementation, step S15 may include:
sending a registration request to the agent process, wherein the registration request comprises the authentication signature;
the proxy process sends the registration request to the server via the HTTP protocol.
That is, based on the generated authentication signature, the terminal device may generate a registration request including the authentication signature. The terminal device may send a registration request to the proxy process, which sends the registration request to the server via the HTTP protocol.
In a possible implementation manner, after receiving the registration request, the server may verify the authentication signature and verify the registration authentication information of the terminal device. The server returns registration information to the terminal device when the authentication signature is successfully verified.
In this way, a registration request process may be implemented.
In one possible implementation, step S16 may include:
the agent process forwards the registration information to the terminal equipment under the condition of receiving the registration information sent by the server;
and the terminal equipment establishes communication connection with the server through the proxy process according to the registration information.
That is, the registration information returned by the server is sent to the proxy process, which forwards the registration information to the terminal device upon receipt. And the terminal equipment establishes communication connection with the server through the proxy process according to the registration information, thereby completing the registration process.
Fig. 3 shows a schematic diagram of the registration phase of a device registration method according to an embodiment of the present disclosure. As shown in fig. 3, the terminal device 31, the proxy process 32, and the server 33 are included. In the registration phase:
in step 3-1, the terminal device 31 sends a registration request to the agent process 32;
in step 3-2, the agent process 32 sends a registration request to the server 33;
in step 3-3, the server 33 returns registration information to the agent process 32 in the case where the authentication signature is successfully verified;
in step 3-4, the proxy process 32 forwards the registration information to the terminal device 31.

Therefore, the encryption chip ensures the confidentiality and the uniqueness of the license authorization file, and ensures that the equipment cannot normally register once the license authorization file is tampered. The registration security certificate of the equipment is placed in the permission authorization file, so that the leakage of the security certificate of the equipment can be avoided even if the equipment is lost. Meanwhile, the limited reading mode of the encryption chip can ensure that the encryption key cannot be leaked to a third party, so that the registration security certificate cannot be leaked, and the security of equipment registration is improved.
