Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for establishing secure wireless networks require manual entry of common authentication keys, which are tedious and slow, discouraging users from using secured networks.
Innovation Solution
Devices generate authentication keys based on physical stimuli, using sensors to detect common stimuli and apply a predetermined algorithm to produce matching keys, allowing for automatic key generation and network establishment without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual entry of common authentication keys is used, then security is maintained, but the process becomes tedious and slow
Solution Approach 1:
The system enables devices to automatically generate and exchange authentication keys without human intervention. Sensors on each device detect physical proximity and automatically create cryptographic key pairs, with public keys exchanged peer-to-peer and private keys stored locally, eliminating the need for manual key entry while maintaining security
Solution Approach 2:
The patent replaces the mechanical process of manual key entry with sensor-based automatic detection and generation. Physical sensors detect proximity events and trigger automated cryptographic key generation and exchange processes, substituting human manual operations with automated electronic systems that are both faster and more secure
2Productivity
If automated key generation is implemented, then speed is improved, but device complexity increases
Solution Approach 1:
The system uses universal sensor components already present in modern devices (accelerometers, gyroscopes, proximity sensors) for authentication purposes. These existing sensors are repurposed to detect proximity events, eliminating the need for specialized hardware and reducing overall system complexity while enabling automated key generation
Solution Approach 2:
The patent introduces a standardized cryptographic library as an intermediary layer that handles the complex key generation and exchange processes. This intermediary abstracts the computational complexity from the hardware level, providing a uniform interface that simplifies integration across different device types while maintaining high-speed automated authentication

AI summary
Methods, systems and devices for generating an authentication key are provided. Two or more communications devices can generate an authentication key by monitoring a physical stimulus that is experienced by both devices (e.g., a common physical stimulus). Each device can then use an identical, predetermined algorithm to generate a common authentication key based on the stimulus. The devices can use the common authentication key to establish a secure network.
