Trusted Proxy Key Exchange for Home Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems require users to repeatedly provide credentials to access and control network devices, both locally and remotely, which is inconvenient and insecure, especially in home automation networks where seamless access is desired without compromising security.
Innovation Solution
A method using a trusted proxy within the network to distribute and manage security keys for access devices, allowing them to authenticate and control network devices without the need for frequent credential entry, by generating and validating unique identifiers with expiration times to ensure secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users repeatedly provide credentials to access network devices, then security is maintained, but user convenience deteriorates
Solution Approach 1:
The system performs preliminary action by pre-establishing and storing security keys and unique identifiers in the trusted proxy before actual access occurs. When a device needs to access network devices, the system retrieves the pre-stored credentials from the trusted proxy, eliminating the need for users to repeatedly provide credentials while maintaining security through pre-validated authentication mechanisms.
2Reliability
If security keys are distributed through a trusted proxy, then access security is improved, but system complexity increases
Solution Approach 1:
The system introduces a trusted proxy as an intermediary component that centralizes the distribution and storage of security keys. This intermediary handles all authentication-related operations, including storing unique identifiers with expiration times, validating credentials, and distributing security keys to authorized devices. By concentrating these functions in a dedicated intermediary, the system improves access security while managing complexity through a clear separation of authentication responsibilities.

AI summary
Techniques for exchanging security keys via a trusted proxy are provided. For example, a method may include receiving, at a computing device, a communication including a unique identifier for an access device connected to a network, wherein unique identifiers include an expiration time. The method may further include using the unique identifier to determine a security key for the access device. The method may also include receiving, at the computing device, a new communication, wherein the new communication includes the unique identifier. The method may further include validating the unique identifier for the access device, wherein validating includes determining whether the unique identifier has expired, and then using the validated identifier to retrieve the security key for the access device. The method may also include transmitting the security key, wherein when the security key is received, the security key facilitates generating a signature.
