Problems solved by technology

The Bluetooth module working in the broadcast mode is generally in a non-connectable state and has no interactivity. It can send broadcast messages to the outside, but cannot receive broadcast messages.
The Bluetooth module working in broadcast mode is limited by computing power and hardware resources. The data is transmitted in clear text. After the data is intercepted, it is easy to be forged, and there are data security issues.

Embodiment approach 1

[0067] Embodiment 1: In this embodiment, in addition to providing keys for third-party manufacturers, the server device 102 can also apply for MAC addresses for locally stored keys, and establish a correspondence between MAC addresses and keys. Wherein, one key corresponds to one MAC address. Based on this, in addition to delivering at least one key to the third-party manufacturer, the server device 102 will also deliver the MAC address corresponding to the at least one key to the third-party manufacturer. For third-party manufacturers, there is no need to apply for a MAC address for their Bluetooth devices, and the MAC address provided by the server device 102 can be used directly, and a key and its corresponding MAC address can be configured to a Bluetooth device under the above product ID. in the device. In this embodiment, the server device 102 may further establish and save the correspondence between the product ID, at least one key, and the MAC address of at least one B...

Embodiment approach 2

[0068] Embodiment 2: In this embodiment, the third-party manufacturer can apply for a MAC address for the bluetooth device 103 produced by itself, and configure the applied MAC address in the bluetooth device 103 . In addition, after receiving at least one key allocated by the server device 102 for the product ID, each key can be configured in a Bluetooth device. For a Bluetooth device configured with a key, it also has its own MAC address. After the third-party manufacturer configures the key issued by the server device 102 to the Bluetooth device, it can report the MAC address of the Bluetooth device where each key is located to the server device 102, so that the server device 102 can learn about each key. The MAC address corresponding to the key, and then establish and save the correspondence between the product ID, each key and the MAC address locally. Wherein, the MAC address and product ID of the Bluetooth device can be used as the identity of the Bluetooth device.

Abstract

The embodiment of the invention provides a data transmission, network distribution and management method, device and system and a storage medium. In the embodiment of the invention, the Bluetooth device or module working in the broadcast mode encrypts the data by using the preset key and then broadcasts the encrypted data outwards, and correspondingly, the server device decrypts the encrypted data by using the locally pre-stored key. In the whole process, the data is encrypted and transmitted, and the key is not transmitted in the air, so that the security of the data is ensured. Besides, when the Bluetooth device or module works in the broadcast mode, the broadcast mode has low requirements on the operational capability and hardware resources of the Bluetooth device or module, so that the implementation cost of the Bluetooth device or module can be reduced.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a data transmission, network distribution and management method, device, system and storage medium. Background technique [0002] Bluetooth Low Energy (Bluetooth Low Energy, BLE) is one of the Bluetooth technologies. Broadcast mode is a common working mode of Bluetooth Low Energy. The Bluetooth module working in the broadcast mode is generally in a non-connectable state and has no interactivity. It can send broadcast messages to the outside, but cannot receive broadcast messages. The Bluetooth module working in the broadcast mode is limited by computing power and hardware resources, and the data is transmitted in plain text. After the data is intercepted, it is easy to be forged, and there are data security problems. Contents of the invention [0003] Various aspects of the present application provide a method, device, system and storage medium fo...
