Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for connecting applications on an Electronic Flight Bag (EFB) to avionics systems in aircraft require cumbersome and time-consuming individual pairing processes for each application, lacking efficient mechanisms for authorized data communication and sharing of specialized data keys.
Innovation Solution
The implementation of a method where a specialized data key is generated and stored within the operating system of an electronic device, allowing subsequent applications to access and utilize this key for authorized communication with avionics systems, reducing the need for repeated pairing and enhancing data exchange efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual pairing processes are used for each application to connect to avionics systems, then security and authorization are maintained, but the pairing process becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges the authorization mechanism by implementing a single pairing process at the operating system level that generates a specialized data key shared across multiple applications. This consolidates what would otherwise require individual pairing for each application, reducing repetitive pairing operations while maintaining security through the shared cryptographic key stored in secure memory.
Solution Approach 2:
The patent performs the authorization action in advance by establishing a single pairing relationship between the electronic device and avionics system before multiple applications need to access data. The specialized data key is generated and stored beforehand in the operating system's secure memory, eliminating the need for repeated pairing operations when applications request data.
2Adaptability or versatility
If multiple applications individually pair with avionics systems, then each application has authorized access, but the system complexity and operational burden increase
Solution Approach 1:
The patent implements a universal authorization mechanism where a single specialized data key generated by the operating system serves multiple applications simultaneously. This multi-functional key allows different applications to access avionics system data without requiring individual pairing, reducing operational burden while maintaining authorized access for each application.
3Reliability
If individual data keys are generated for each application, then security is maintained, but data communication efficiency decreases
Solution Approach 1:
The patent merges the authorization approach by using a single specialized data key for multiple applications communicating with avionics systems. This eliminates the overhead of generating, managing, and processing individual keys for each application, thereby improving data communication efficiency while maintaining security through the shared cryptographic authentication mechanism.
