1Use of energy by moving object
If conventional cryptographic systems are used in space vehicles, then data encryption can be performed, but the systems consume excessive power and have limited bandwidth
Solution Approach 1:
The cryptographic system is divided into multiple independent cryptographic modules (CMEIs) that can process data packets in parallel. Each module handles a portion of the data stream, enabling the system to achieve high bandwidth throughput while maintaining low power consumption per module. The input module distributes packets across multiple CMEIs, and the output module collects results, creating a scalable architecture where power consumption can be managed independently from total processing capacity.
2Productivity
If multiple cryptographic modules are used to increase bandwidth, then data throughput is improved, but device complexity increases
Solution Approach 1:
Multiple cryptographic modules are integrated onto a single integrated circuit board, sharing common input and output modules as well as power management resources. This merging approach allows the system to achieve high throughput through parallel processing while reducing overall complexity by eliminating redundant components. The shared input module handles packet distribution and the shared output module consolidates results, reducing the total component count compared to separate cryptographic systems.
3Reliability
If cryptographic modules are continuously activated to maintain security, then security is ensured, but power consumption increases
Solution Approach 1:
The system implements dynamic power management where the electronic processor can selectively activate or deactivate specific cryptographic modules based on real-time security requirements and power availability. This dynamic control allows the system to maintain security by keeping essential modules active while powering down less critical modules during low-power periods, achieving a balance between security continuity and power consumption that static configurations cannot provide.
