BLE Pre-authorization Security Exchange for Reduced Pairing Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Bluetooth pairing process for information handling systems is delayed due to the need for user input to initiate security protocols, leading to increased wait times and a negative user experience.
Innovation Solution
The implementation of a pre-authorization security exchange system that generates and stores pre-authorization passcode entry information prior to user confirmation, allowing for parallel processing and reduced wait times by detecting user presence and initiating security exchanges automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system waits for user input to initiate security protocols during Bluetooth pairing, then security verification can be performed, but pairing time increases and user experience deteriorates
Solution Approach 1:
The system performs pre-authorization security exchange before user confirmation by generating and exchanging cryptographic credentials (public keys, signatures, nonces) in advance. This preliminary security verification allows the pairing process to resume quickly when the user returns, eliminating the need to wait for user input during critical security protocols.
Solution Approach 2:
The system automatically manages the pairing process by detecting user presence through sensors (camera, microphone, sensors) and autonomously initiating security protocols without requiring manual user intervention. The system serves itself by monitoring user state and executing appropriate pairing actions based on detected presence.
2Ease of operation
If the system performs security exchange after user confirmation, then user control is maintained, but pairing delay increases
Solution Approach 1:
Security credentials and authorization data are exchanged and cached in advance before user confirmation. The system prepares all necessary security parameters (public keys, signatures, nonces) beforehand, so when the user confirms pairing, the process can complete immediately without time-consuming security exchanges.
Solution Approach 2:
The system introduces an intermediate caching mechanism that stores pre-exchanged security credentials. This intermediary cache allows the system to decouple the security exchange from user confirmation timing, maintaining user control while eliminating pairing delays by retrieving pre-prepared credentials from cache.
3Loss of time
If the system initiates pre-authorization before user confirmation, then pairing time is reduced, but system complexity increases
Solution Approach 1:
The system implements pre-authorization by generating cryptographic pairs, exchanging public keys, and caching authorization data before user confirmation. This preliminary setup reduces pairing time by having security credentials ready in advance, managed through structured data models and caching mechanisms.
Solution Approach 2:
The system replaces manual user-driven pairing mechanics with automated sensor-based detection and algorithmic presence determination. Sensors (camera, microphone, motion sensors) and machine learning models substitute for manual user actions, reducing pairing time while managing complexity through automated decision-making systems.
4Extent of automation
If the system uses sensor-based user presence detection, then automatic pairing initiation is enabled, but device complexity increases
Solution Approach 1:
The system automatically detects user presence using sensors (camera, microphone, motion sensors) and autonomously initiates pairing without manual user input. The system serves itself by monitoring its environment and executing pairing actions based on detected user state, enabling automatic pairing initiation.
Solution Approach 2:
Manual user actions for initiating pairing are replaced with sensor-based detection systems. The system uses cameras, microphones, and motion sensors combined with machine learning models to automatically determine user presence and trigger pairing, substituting mechanical user interaction with automated sensing and decision-making.

AI summary
An information handling system includes a hardware processor executing computer readable program code of a user presence detection system to detect interactions of a user with the information handling system to determine pairing priority. Further, the hardware processor executes computer readable program code of a pre-authorization security exchange system to communicate with a wireless peripheral device to receive or generate pre-authorization passcode entry information and to initiate a security exchange communication to authorize Bluetooth® (BT) pairing pending a user decision to accept the pairing to reduce pairing time. The pre-authorization security exchange system stores the pre-authorization passcode entry information in a memory device for authorization or for a later retry and, if authorized and pairing accepted, a wireless interface adapter will BT pair the information handling system and the wireless peripheral device.
