Referring to fig. 1-3, in one embodiment of the first aspect of the present invention, there is provided a bluetooth keyless entry smart lock method, comprising the steps of:
s1: performing broadcast scanning; the broadcasting scanning is continuously carried out on the surrounding environment, and when a user carries a Bluetooth function mobile phone or a key ring made of BLE Bluetooth, the mobile phone can be scanned within the range of 1-2 meters close to the door lock system.
S2: receiving a response data packet obtained by broadcast scanning; when a user carries a Bluetooth function mobile phone or a key ring made of BLE Bluetooth and approaches to a door lock, the door lock system senses a Bluetooth device signal carried by the user and acquires a corresponding data packet. Wherein the data distribution in the response packet is as follows in table 1:
| byte 1 | Byte 2 | Byte 3 | Byte 4 | ………… | Nth byte |
| Total length of | 0xFF | XX | XX | XX | XX |

S3: judging whether the obtained response data packet meets the format requirement, executing the step S4 when the response data packet meets the format requirement, otherwise, returning to execute the step S1; according to the data distribution condition of the response data packet in the table 1, the invention can prove that the response data packet accords with the format requirement by judging whether the data in the 2 nd byte in the response data packet is 0xFF preset by the system or not and when the data in the 2 nd byte in the response data packet is 0 xFF; when the data in the 2 nd byte of the response data packet is not 0xFF, the response data packet is proved to be not in accordance with the format requirement.
S4: AES decryption processing is carried out on the response data packet; since the received response packet is replay-attacked by illegal modification and copying in order to prevent the data from being hacked, AES encryption processing is performed in advance. Therefore, after the response data packet is received, AES decryption processing is required for the response data packet, and after the data packet in table 1 is subjected to AES decryption processing based on the response data packet meeting the format requirement, table 2 can be obtained as follows:
| byte 1 | Byte 2 | 3 rd to 7 th byte | 8 th to 13 th byte | 14 th to 15 th byte | 16 th to 23 rd byte |
| Total length of | 0xFF | Time stamp | MAC address | Instruction bits | MD5 |

S6: judging whether the time of the data is effective, executing the step S7 when the time is effective, otherwise, returning to execute the step S1; the invention can judge whether the time difference between the time stamp of the data after the AES decryption processing and the system time is in the preset time difference range, and considers the time to be effective when the time difference is in the preset time difference range, and considers the time to be ineffective when the time difference is not in the preset time difference range. For example, since the 3 rd to 7 th bytes in table 2 after the decryption process are used to store the time stamp data, when judging whether the time of the data is valid, the time stamp data in the 3 rd to 7 th bytes may be directly compared and judged. Secondly, the preset time difference range in the invention is three minutes, namely whether the time difference between the time stamp and the local system is within three minutes or not can be judged, the time of the data is considered to be valid when the time difference is within three minutes, and the time of the data is considered to be invalid when the time difference is not within three minutes.
S7: judging whether the data is legal, executing the step S9 when the data is legal, otherwise, returning to the step S1; finally, the validity of the data needs to be judged.

s9-1: the current mode is a normal mode, and step S9-2 is executed;
s9-2: judging whether an MAC address consistent with the data after AES decryption processing exists in the MAC addresses prestored in the system, executing the step S9-3 when the consistent MAC address exists, otherwise executing the step S12; since the 8 th to 13 th bytes in the table 2 after decryption processing are used for storing the MAC addresses, when judging whether the MAC addresses consistent with the data after AES decryption processing exist in the MAC addresses pre-stored in the system, the comparison and verification are directly performed on the MAC addresses in the 8 th to 13 th bytes.
S9-3: judging whether the vehicle is in an unlocking state or a locking state currently, executing the step S9-4 when the vehicle is in the unlocking state, and executing the step S9-5 when the vehicle is in the locking state;
s9-4: updating the automatic locking time;
s9-5: outputting an unlocking signal and prompting successful unlocking;
s12: and prompting failure.

the data instruction bit type judging unit is used for judging the type of the instruction bit of the data subjected to the AES decryption processing, and when the type of the instruction bit is a comparison instruction, the key matching processing is executed; when the category of the command bit is the input command, executing key input processing; when the category of the instruction bit is a deleting instruction, executing key deleting processing;
the key input processing unit is used for judging whether an MAC address consistent with the data after the AES decryption processing exists in the MAC addresses prestored in the system, if so, inputting cannot be performed, and input failure is prompted, and if not, inputting the MAC address of the data after the AES decryption processing, and prompting that input is successful;
the key deleting processing unit is used for judging whether the MAC address which is consistent with the data after the AES decryption processing exists in the MAC addresses which are prestored in the system, deleting the corresponding MAC address which is prestored in the system when the consistent MAC address exists, prompting that the deletion is successful, and failing to delete when the consistent MAC address does not exist.
4. A bluetooth keyless entry device according to claim 3, further comprising the following elements:
and the lock body state judging unit is used for judging whether the lock body is in an unlocking state or a locking state currently, updating the automatic locking time when the lock body is in the unlocking state, and outputting an unlocking signal when the lock body is in the locking state.
5. A bluetooth keyless entry device, characterized by: comprising at least one control processor and a memory for communication connection with the at least one control processor; the memory stores instructions executable by the at least one control processor to enable the at least one control processor to perform a bluetooth keyless entry smart lock method according to claim 1 or 2.
6. A computer-readable storage medium, characterized by: the computer readable storage medium stores computer executable instructions for causing a computer to perform a bluetooth keyless entry smart lock method according to claim 1 or 2.
