The mode of obtaining the authentication information in the encryption out-of-band mode can be that the headquarters sends information in the format of encrypted authentication two-dimensional codes and the like of the equipment to the operator in advance in the modes of mails, telephones, short messages and the like.
Specifically, the authentication information may be a UUID (universal Unique Identifier) key of the DTU device, and the UUID of the DTU device may be obtained by combining an SN code of the DTU device and an IMEI (International Mobile Equipment Identity) and encrypting the SN code. The UUID key of the DTU equipment can be obtained after the UUID is processed or distributed by the server.
Specifically, as shown in fig. 2, fig. 3, and fig. 4 are authentication flowcharts of the DTU device when the DTU device is authenticated for the first time in a factory state, when the DTU device completes authentication and connection with the server, and when the DTU device is restored to the factory setting after the DTU device completes authentication, respectively, as can be seen from fig. 2, fig. 3, and fig. 4, an embodiment of the method for acquiring a UUID of the DTU device may be:

In step 304, the mobile terminal receives information whether the source of the UUID key is the server, and updates the UUID index of the DTU device and the corresponding UUID in an out-of-band manner if necessary.
Specifically, when the DTU device is in a factory state and is authenticated for the first time, the source of the UUID key is not the server, and at this time, the UUID index and the corresponding UUID of the DTU device do not need to be updated.
When the DTU equipment and the server finish authentication and connection, the source of the UUID key is the server, and at the moment, the mobile terminal updates the UUID index of the DTU equipment and the corresponding UUID in an out-of-band mode when needed.
When the factory setting is restored after the DTU equipment and the server finish authentication, the source of the UUID key is not the server, the mobile terminal judges that the source of the UUID key is wrong after receiving the message, informs the server that the DTU equipment restores the factory setting, and updates the UUID index of the DTU equipment and the corresponding UUID.
Preferably, in an embodiment of the method for configuring the device through the portable mobile terminal provided by the present invention, after the DTU device determines that the UUID key of the mobile terminal is correct, the DTU device further determines the correctness of the key, where the key is generated by combining the UUID of the DTU device, the communication protocol version of the mobile terminal, and the communication protocol version of the DTU device.
Specifically, the connection request information sent by the mobile terminal to the DTU device in step 302 includes the mobile terminal information and the mobile terminal communication protocol version.
In step 305, after the DTU device determines that the UUID key is correct, the method further includes:
step 306, the DTU device sends information of whether the mobile terminal is in a factory state, a communication protocol version of the DTU device and a UUID to the mobile terminal.
And 307, the mobile terminal generates a key according to the combination of the UUID of the DTU equipment, the communication protocol version of the mobile terminal and the communication protocol version of the DTU equipment, and sends the key encrypted by the MD5 to the DTU equipment.
And 308, when the DTU equipment judges that the secret key is correct, the authentication is confirmed to pass, and when the secret key is judged to be wrong, the authentication process is interrupted.
After the authentication is completed, the mobile terminal and the DTU equipment perform operations such as equipment state checking, equipment configuration and the like according to a predefined protocol.
The management instruction format is as follows:
