Secure Wireless Connection via Temporary Credential Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication methods face security challenges due to the ease of intercepting and guessing simple passcodes, which compromises the security of wireless connections between electronic devices.
Innovation Solution
A method involving a server-generated temporary code is used to establish a secure wireless connection by creating temporary and secure credentials, allowing for a lower-security code that is easy to remember while enhancing security through a multi-step authentication process involving wake-up codes and secure communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex passcodes are used to protect wireless communication channels, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The authentication process is divided into two distinct phases: first, a simple passcode is used for initial connection establishment, then a separate secure credential exchange occurs through the temporary connection. This segmentation allows each phase to use appropriately complex credentials without burdening the user with remembering both.
Solution Approach 2:
A temporary connection acts as an intermediary channel between the first and second electronic devices. This temporary connection facilitates the secure exchange of credentials without requiring the user to manually handle complex security protocols, thereby maintaining both security and ease of operation.
2Ease of operation
If simple passcodes are used to improve ease of operation, then ease of operation is improved, but security deteriorates
Solution Approach 1:
A temporary connection is established beforehand using the simple passcode. This preliminary action creates a secure channel through which complex credentials can be exchanged automatically, eliminating the need for users to handle complex security information while maintaining strong security.
Solution Approach 2:
The electronic devices automatically perform the secure credential exchange and authentication processes through the temporary connection without requiring user intervention. The system handles the complex security protocols autonomously, allowing users to simply enter the simple passcode.
3Reliability
If continuous wireless communication is maintained for security, then security is improved, but power consumption increases
Solution Approach 1:
The temporary connection is activated only during the credential exchange period and then disconnected. This periodic activation ensures that wireless communication occurs only when necessary for security credential transmission, minimizing power consumption while maintaining security during critical operations.
