Embodiment 1
[0033] Embodiment 1 of the present invention provides a method for importing data in batches, including:
[0034] In advance, when Bluetooth devices are mass-produced, before the security chip is welded, the Bluetooth MAC address segment and personalized data (including but not limited to Bluetooth card personal data) authorized by the IEEE (Institute of Electrical and Electronics Engineers) will be downloaded through the personalized data download tooling. , communication protocol data, etc.) are written into the security chip storage area of the Bluetooth device. Wherein, the Bluetooth MAC address is characteristic data of the Bluetooth chip, and the personalized data is characteristic data of the security chip.
[0035] The specific writing method is:
[0036] The personalized data downloading tool has built-in multi-channel security chip downloading boards, and each security chip downloading board is connected to the corresponding chip fixture in the personalized data d...
Embodiment 2
[0045] Embodiment 2 of the present invention provides a method for writing Bluetooth MAC addresses in batches, such as figure 2 As shown, a Bluetooth device performs the following actions on power-up:
[0046] Step 21: The Bluetooth chip reads the Bluetooth MAC address from the security chip storage area;
[0047] In this embodiment, the specific operation of the bluetooth chip to read the bluetooth MAC address is:
[0048] Step 211: establishing a secure channel between the bluetooth chip and the security chip;
[0049] like image 3 As shown, the establishment of a secure channel is specifically:
[0050] Step 31, the Bluetooth chip generates a session key, encrypts the session key with the encryption key, and sends the encrypted result to the security chip;
[0051] Step 32, the security chip uses the decryption key to decrypt the encrypted result, and stores the decrypted data as a session key;
[0052] Step 33, the security chip generates a random number, encrypts t...
