BLE Double Authentication for Server Node Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Bluetooth low energy authentication lacks robust security measures, making it vulnerable to attacks, especially when managing server nodes without a wired connection, as it relies solely on device trust and passkey verification.
Innovation Solution
Implementing a double authentication mechanism using near-field communication and button authorization, which can be either NFC-only, button-only, or a combination of both, to enhance security when managing server nodes via a mobile device, ensuring a second challenge for added security and management connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional Bluetooth low energy authentication is used, then ease of operation is improved, but security is worsened
Solution Approach 1:
The authentication process is segmented into two distinct phases: initial Bluetooth low energy connection establishment using traditional authentication, and a second near-field communication authentication phase. This segmentation allows each phase to serve its specific purpose while collectively providing both ease of operation and enhanced security.
Solution Approach 2:
Near-field communication serves as an intermediary authentication mechanism between the mobile device and server node. The NFC requirement acts as a mediator that verifies physical proximity and user intent, adding a security layer without significantly complicating the user experience.
2Reliability
If double authentication is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The authentication system dynamically adapts its complexity based on the situation. The dual authentication mechanism is not always mandatory - the system can operate with just Bluetooth authentication when security requirements are lower, and only requires NFC additionally when managing critical server nodes, making the complexity adaptive rather than static.
3Reliability
If near-field communication is required, then security is improved, but ease of operation is worsened
Solution Approach 1:
The Bluetooth low energy connection is established in advance as a preliminary step before the NFC authentication is required. This preliminary action allows the system to prepare the communication channel and context beforehand, so that when NFC authentication is triggered, the user experience remains smooth and intuitive.

AI summary
Disclosed are systems, methods, and computer-readable storage media for Bluetooth low energy (BLE) double authentication between a mobile device and server nodes. A system using BLE authentication can receive at a mobile device, an identifier of a dongle attached to a server that enables wireless communication and can establish a wireless low energy connection with the dongle without paring. The system can receive a server identifier and can determine whether the server has previously been authenticated to yield a determination. When the determination is that the server has not previously been authenticated, the system can receive a baseband management controller username and a password. When the determination is that the server has previously been authenticated, the system can determine whether to perform a double authentication to yield a second determination. The system can perform the double authentication when the second determination indicates that the double authentication should be performed.
