Lead Device Authentication for Secure Secondary Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data encryption methods between devices in a network lack secure and efficient authentication processes, particularly for secondary devices, which can lead to insecure data transmission and increased connection establishment times.
Innovation Solution
A method is introduced where a lead device authenticates secondary devices using credentials such as public keys and passwords, establishing a secure SSH tunnel for data transmission, and automatically re-establishes connections upon device reactivation, reducing connection time and ensuring secure data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used for secondary devices, then connection establishment is simpler, but security of data transmission is compromised
Solution Approach 1:
The patent implements preliminary authentication actions by establishing credential verification processes before data transmission begins. The lead device stores credentials of secondary devices in advance, and performs authentication checks before allowing connections, ensuring security is built into the connection establishment process rather than added later.
2Reliability
If manual connection establishment is used, then authentication can be thorough, but connection establishment time increases
Solution Approach 1:
The system performs preliminary authentication by checking stored credentials against connection requests before full connection establishment. This allows rapid verification for returning devices while maintaining security, reducing connection establishment time without compromising authentication thoroughness.
3Loss of information
If secure authentication protocols are implemented, then data privacy is protected, but connection establishment becomes slower
Solution Approach 1:
The patent implements preliminary authentication using stored credentials and device identifiers before full secure connection establishment. This two-stage approach allows rapid initial verification followed by secure data transmission, protecting data privacy while minimizing connection establishment time.

AI summary
Techniques for establishing a secure connection between a lead device and a secondary device are disclosed herein. According to an embodiment, the lead device receives a request to establish a secure connection with the secondary device. The lead device determines whether the secure connection is an initial connection with the secondary device. In response to a determination that the secure connection is not an initial connection with the secondary device, the lead device authenticates the secondary device using one or more credentials associated with the secondary device and stored by the lead device. In response to a successful authentication using the one or more credentials, the lead device establishes the secure connection with the secondary device.
