Airborne Server for Secure Avionic Data Dissemination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerospace networks, such as ACARS, restrict access to avionic operational data due to limited bandwidth and messaging capabilities, and are primarily limited to cockpit instrumentation, hindering efficient aircraft fleet operations and communication.
Innovation Solution
A programmable portable electronic device (PED) is introduced, connected to an airborne server, which implements security measures to prevent unauthorized access and allows for the dissemination of avionic operational data to designated devices, enabling secure and flexible communication beyond cockpit limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ACARS datalink communication is used for transmitting avionic operational data, then data can be communicated to fleet control center, but bandwidth is limited and messaging capabilities are restricted
Solution Approach 1:
The system segments data communication into two pathways: traditional ACARS for essential operational data and the new wireless network for bulk data transfer. This segmentation allows high-bandwidth data transmission while maintaining backward compatibility with existing ACARS infrastructure, resolving the bandwidth limitation without sacrificing communication efficiency.
Solution Approach 2:
The airborne server acts as an intermediary between aircraft systems and external networks. It receives avionic operational data from aircraft systems, processes and secures the data, then transmits it through multiple channels including ACARS and wireless networks. This intermediary role enables flexible data routing that overcomes ACARS bandwidth limitations.
2Ease of operation
If access to avionic operational data is limited to cockpit instrumentation, then data security is maintained, but accessibility for fleet operations is reduced
Solution Approach 1:
The system implements different security characteristics for different data access scenarios. Cockpit instrumentation maintains strict security controls, while authorized remote devices receive appropriate levels of access based on their security credentials and operational needs. This localized security approach enables broader accessibility without compromising critical security requirements.
Solution Approach 2:
The airborne server serves as a secure intermediary that controls data dissemination to portable electronic devices. It authenticates devices, encrypts data transmissions, and manages access rights, thereby enabling remote data accessibility while maintaining security through centralized control and verification mechanisms.
3Adaptability or versatility
If portable electronic devices are allowed to access avionic operational data, then communication flexibility is improved, but unauthorized access risk increases
Solution Approach 1:
The system performs preliminary authentication and authorization checks before allowing any portable electronic device to access avionic operational data. The airborne server verifies device legitimacy, user credentials, and access rights in advance, establishing a secure foundation that enables flexible communication while preventing unauthorized access from the outset.
Solution Approach 2:
The airborne server acts as a security intermediary between aircraft systems and portable electronic devices. It implements encryption, authentication, and access control mechanisms that protect against unauthorized access while allowing legitimate devices to communicate flexibly with aircraft systems.
