Method and system for secured pairing for data communication between an edge node and a bluetooth device

A method for establishing a secured connection for data transmission, comprising:

• generating a first digital certificate for an a line replaceable unit (LRU) comprising a hardware device with embedded software for a secured wireless data communications link, where the first digital certificate verifies the identity of the LRU and enables encrypted connections;
• generating a second digital certificate for a mobile device that uses a Bluetooth wireless communications standard protocol, where the second digital certificate verifies the identity of the mobile device and enables encrypted connections;
• scanning for a generic attribute (GATT) Bluetooth profile of the LRU with the mobile device;
• generating an encrypted pairing key for the LRU and sharing it with the mobile device through the GATT Bluetooth profile upon matching the GATT properties of the LRU with the mobile device;
• initiating an encrypted connection between the LRU and the mobile device using the encrypted pairing key, where the encrypted connection utilizes the Bluetooth wireless communications standard protocol;
• and establishing an encrypted data channel between the LRU and the mobile device upon successfully pairing the LRU and the mobile device by, exchanging the first digital certificate and the second digital certificate for authentication, and exchanging rivest-shamir-adelman (RSA) encryption keys between the and the mobile device for data encryption.
