Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collaborative device users within close proximity often face challenges in establishing a secure and authenticated peer-to-peer connection without sharing security credentials, relying on conventional methods that lack robust authentication.
Innovation Solution
A method that involves recording the time of a tapping event between devices, establishing a non-authenticated secure link, and verifying the target device through a challenge-response mechanism using cryptographic protocols to ensure secure authentication, with higher resolution time data enhancing security accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional email/message exchange method is used, then users can communicate without sharing security credentials, but secure authenticated peer-to-peer connection cannot be established
Solution Approach 1:
The system performs preliminary actions by having devices record tapping event time data before the actual connection is needed. This pre-recording of time stamps during the physical tapping event enables later authentication without requiring users to manually share credentials, thus improving security while maintaining ease of operation.
Solution Approach 2:
The patent introduces time data of tapping events as an intermediary element that mediates between two devices. Instead of directly sharing security credentials, devices use the recorded time data as a shared secret that proves mutual participation in the tapping event, enabling authentication without credential exchange.
2Reliability
If time data accuracy is increased for higher authentication security, then device clock synchronization precision must be improved
Solution Approach 1:
The system changes the parameter of time measurement resolution to achieve higher authentication accuracy. By using high-resolution time stamps with millisecond or microsecond precision, the system can accurately distinguish between different tapping events and prevent replay attacks, thus improving authentication reliability through parameter optimization.
