Enterprise Wireless Peripheral Pairing via Backend Key Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manual Bluetooth pairing process for wireless peripheral devices with information handling systems is insecure and cumbersome, requiring user input and potentially allowing third-party access, while also being inefficient in automating the pairing process across multiple devices.
Innovation Solution
A backend management server generates temporary keys and peripheral device IDs, which are sent to both the peripheral devices and managed information handling systems, enabling automatic querying, verification, and secure Bluetooth pairing through a hash function and encrypted communication, ensuring secure and efficient pairing across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual Bluetooth pairing process is used, then user control and device compatibility are maintained, but security is compromised and user operation becomes cumbersome
Solution Approach 1:
The system performs preliminary actions by pre-provisioning peripheral devices with unique identifiers and cryptographic keys before pairing. The backend server automatically generates and distributes pairing credentials to both the information handling system and peripheral device in advance, eliminating the need for manual user input during pairing while maintaining security through pre-established trust relationships.
Solution Approach 2:
A backend server acts as an intermediary between the information handling system and peripheral devices. It manages the pairing process by verifying device identities, distributing cryptographic credentials, and orchestrating the pairing sequence, thereby automating security checks that would otherwise require manual user intervention.
2Productivity
If automated pairing process is implemented, then pairing efficiency and productivity are improved, but system complexity increases
Solution Approach 1:
The complex pairing logic and cryptographic verification processes are extracted from the endpoint devices (information handling systems and peripheral devices) and centralized in the backend server. This allows the endpoint devices to perform simple automated pairing operations while the server handles the computational complexity of key management and security verification.
Solution Approach 2:
The backend server provides a universal pairing solution that works across multiple different peripheral devices and information handling systems. By implementing a standardized automated pairing protocol on the server side, the system achieves high productivity across diverse device types without requiring complex device-specific customization at the endpoint.
3Reliability
If manual pairing verification is performed, then device authentication security is maintained, but time consumption increases
Solution Approach 1:
Authentication credentials including cryptographic keys and device identifiers are pre-provisioned on both the peripheral devices and information handling systems before pairing occurs. The backend server generates these security credentials in advance and distributes them automatically, enabling rapid verification without time-consuming manual authentication steps while maintaining strong security through pre-established cryptographic relationships.
