In this embodiment, there is provided a method for acquiring device control data of the target bluetooth device, and fig. 3 is a flowchart of a method for acquiring device control data according to an embodiment of the present invention, where the flowchart includes the following steps:

step S202, when the target bluetooth device authorizes the target object to authenticate, key information is sent to the terminal of the target object, where the key information includes: a KEY ID and a KEY KEY, wherein the KEY ID and the KEY KEY have a one-to-one correspondence;

it may be appreciated that, after the target object is authorized by the target bluetooth device in the authentication mode, the target bluetooth device sends a KEY ID and a KEY having a correspondence to the terminal, where the correspondence includes one or more types.

Step S204, receiving the encrypted data and the KEY ID which are sent by the terminal and encrypted according to the KEY KEY;

optionally, under the condition that the KEY information sent by the target Bluetooth device to the terminal only has the KEY ID and the KEY of one corresponding relation, the data are directly encrypted according to the KEY to obtain encrypted data, under the condition that the KEY information sent by the target Bluetooth device to the terminal has the KEY ID and the KEY of multiple corresponding relations, the terminal side can select a designated KEY from the KEY IDs and KEY KEYs of various corresponding relations to encrypt the data, and send the encrypted data and the KEY ID corresponding to the designated KEY to the target Bluetooth device;

In step S206, in the case that the KEY corresponding to the KEY ID is queried through the target bluetooth device, the encrypted data is decrypted according to the KEY corresponding to the KEY ID, where the target bluetooth device stores a plurality of groups of KEY IDs and KEY KEYs having a one-to-one correspondence.

After receiving the data and the KEY ID which are sent by the terminal of the target object and are encrypted by the KEY information, the target Bluetooth device searches the KEY corresponding to the KEY ID according to the KEY ID, decrypts the encrypted data received by the target Bluetooth device, and completes the data interaction between the terminal of the target object and the target Bluetooth device.

Through the steps, under the condition that the target Bluetooth equipment authorizes the target object to carry out authentication, key information is sent to the terminal of the target object through the target Bluetooth equipment, wherein the key information comprises: a KEY ID and a KEY KEY, wherein the KEY ID and the KEY KEY have a one-to-one correspondence; receiving encrypted data which is sent by the terminal and is encrypted according to the KEY and the KEY ID; the target Bluetooth equipment inquires a KEY corresponding to the KEY ID and decrypts the encrypted data according to the KEY corresponding to the KEY ID, wherein the target Bluetooth equipment stores a plurality of groups of KEY IDs and KEY KEYs which have a one-to-one correspondence, namely, through the technical scheme of the invention, the terminal can encrypt the data to be transmitted according to the KEY transmitted by the target Bluetooth equipment and transmit the encrypted data to the target Bluetooth equipment so as to decrypt the target Bluetooth equipment, thereby solving the problems of low security and the like in the prior art when data plaintext authentication is carried out based on BLE GATEE, improving the security of the data in the BLE network and ensuring the security and flexibility of the data when the data plaintext authentication is carried out by Bluetooth pairing.
