Bluetooth technology as a common short-distance wireless communication technology, increasingly used in industrial union scene data transmission between devices, but because of its wireless features facing equipment mutual authentication, data transmission security, the bluetooth security protocol still exist loopholes, bluetooth security mechanism is difficult to meet the requirements of high security environment. From the perspective of lightweight and security, this paper defines the concept of secure transmission without Certificate Authority(CA) certificate participation. Based on Bluetooth Software Development Kit (BLE SDK), it analyzes the characteristics of the Bluetooth protocol layer and the application layer, and puts forward the mutual authentication and encryption and decryption method based on the national secret algorithm and private algorithm, so as to provide support for the security service of the application layer. Finally, the effectiveness of the proposed method is verified by using in power operation and maintenance scenarios.
