Virtual Transponder Inband Commanding for Secure Payload Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transponders lack resource allocation privacy, as they are controlled by a single satellite controller without secure communication protocols, leading to potential security vulnerabilities.
Innovation Solution
Implementing a method and system for virtual transponders that utilize inband commanding with encrypted communication security (COMSEC) to securely transmit and decrypt commands and telemetry between a hosted payload operation center, spacecraft operations center, and vehicle payloads, allowing for secure reconfiguration of transponder settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single satellite controller is used to command and control transponder switching, then device complexity is reduced, but resource allocation privacy and security are compromised
Solution Approach 1:
The patent segments the single satellite controller into multiple virtual transponders, each with its own dedicated controller. This segmentation allows each virtual transponder to have private resource allocation and independent control, resolving the security issue while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent introduces encrypted communication channels as intermediaries between controllers and transponders. These encrypted channels serve as mediators that protect resource allocation privacy while allowing control commands to pass through, thus maintaining system functionality while enhancing security.
2Reliability
If encrypted communication with dual COMSEC varieties is implemented, then resource allocation privacy is enhanced, but device complexity and processing overhead increase
Solution Approach 1:
The patent implements a universal encryption framework where dual COMSEC varieties are integrated into the existing command and control infrastructure. The encryption system performs multiple functions including command encryption, telemetry encryption, and authentication, reducing overall system complexity despite the added security layer.
Solution Approach 2:
The patent changes the encryption parameters by implementing dual COMSEC varieties at different hierarchical levels. This parameter change allows the system to balance security requirements with processing capabilities, applying stronger encryption where needed and lighter encryption where sufficient, thus managing complexity while maintaining privacy.
3Reliability
If virtual transponder architecture with multiple controllers is implemented, then resource allocation privacy is improved, but device complexity increases
Solution Approach 1:
The patent segments the monolithic controller architecture into multiple independent virtual transponder controllers. Each segment operates autonomously with its own encryption key and control logic, providing resource allocation privacy while keeping individual controller complexity low through division of labor.
Solution Approach 2:
The patent implements dynamic controller allocation where virtual transponders can be activated or deactivated based on demand. This dynamic architecture allows the system to scale complexity according to operational needs, maintaining simplicity when fewer virtual transponders are active and providing enhanced privacy when more are activated.
