Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an increasing demand for radio frequency spectrum due to the growing use of wireless communication devices, yet parts of the RF spectrum remain largely unused, necessitating improved methods for sharing and managing telecommunication resources.
Innovation Solution
The implementation of a spectrum management firewall (SMF) system that dynamically shares spectrum between commercial networks and protected system networks by determining potential interference, suppressing frequencies in commercial networks, and using generative adversarial networks (GANs) to generate fake data and mask activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum is shared between commercial networks and protected system networks, then resource utilization is improved, but interference between networks increases
Solution Approach 1:
A spectrum management firewall is introduced as an intermediary system between commercial networks and protected system networks. This firewall monitors spectrum usage, identifies potential interference, and dynamically suppresses frequencies in commercial networks to protect protected system networks, enabling safe spectrum sharing while preventing harmful interference.
Solution Approach 2:
The system dynamically adjusts spectrum allocation and suppression decisions in real-time based on current network conditions. The spectrum management firewall continuously monitors usage patterns and adapts frequency suppression to match changing operational requirements of protected systems, optimizing both utilization and protection.
2Object-affected harmful factors
If frequencies are suppressed in commercial networks to protect protected system networks, then interference is reduced, but spectrum utilization decreases
Solution Approach 1:
Instead of suppressing all frequencies that might potentially cause interference, the system applies partial suppression only when and where interference is actually detected or predicted. The spectrum management firewall uses characteristic information to identify specific frequencies and geographic areas requiring suppression, allowing commercial networks to utilize remaining spectrum resources freely.
Solution Approach 2:
The system changes suppression parameters dynamically based on protected system operational states. When protected systems are active, suppression is applied to specific frequencies; when protected systems are inactive, suppression is reduced or removed, allowing commercial networks to maximize utilization of previously suppressed frequencies.
3Object-affected harmful factors
If characteristic information from protected system networks is transmitted to commercial networks, then interference management is improved, but security and privacy of protected systems deteriorates
Solution Approach 1:
The spectrum management firewall extracts only the essential characteristic information needed for interference management (such as frequency ranges and geographic areas) while leaving sensitive operational details within the protected network. This selective extraction enables effective interference coordination without exposing proprietary or security-critical information about protected system operations.
Solution Approach 2:
The firewall acts as a secure intermediary that processes characteristic information within the protected network boundary. It transforms detailed operational data into anonymized suppression parameters before transmitting to commercial networks, maintaining security while enabling effective interference management.
4Reliability
If generative adversarial networks are used to generate fake data for obfuscation, then security is improved, but system complexity increases
Solution Approach 1:
The generative adversarial network creates synthetic copies of protected system operational patterns that resemble real operations but contain no actual sensitive information. These fake data copies are used to obfuscate real operational characteristics, making it difficult for external observers to distinguish between real and simulated activity while preserving security.
Data Source
AI summary
Methods and systems for detecting and masking activity of resources in a protected system. A Spectrum Management Firewall (SMF) device may be tasked with gathering and categorizing data concerning the operations of network assets. The SMF may train a discriminator neural network using the categorized data and integrate it into a Generative Adversarial Network (GAN) that includes a generator neural network. The discriminator may discern between authentic and fabricated operational data and the generator may create deceptive data that mimics the functionality of fictitious assets corresponding to the recognized resource. The GAN may generate fake systems for every identified resource or the network as a whole. The SMF device may cause a suitable generated fake system to serve as a mask for the activity of a resource in the protected system.
