Solution Overview
Problem
Existing communication networks face challenges in securing wireless communications against eavesdropping, as sensing signals used for integrated sensing and communication (ISAC) can expose communication signals to potential eavesdroppers, compromising security.
Innovation Solution
Implementing sensing-assisted range control techniques that utilize mono-static and bi-static sensing models to detect eavesdroppers, adjusting transmission power levels to prevent signal exposure to eavesdroppers while maintaining effective communication, including updates to power control parameters and signaling protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensing signals are used for integrated sensing and communication, then sensing capability is improved, but communication security deteriorates due to exposure to eavesdroppers
Solution Approach 1:
The patent applies local quality by adjusting transmission power specifically in directions or regions where eavesdroppers are detected, rather than uniformly reducing power everywhere. The base station uses sensing information to identify eavesdropper locations and applies power control selectively to affected communication links, maintaining normal communication quality in secure directions while reducing exposure in compromised directions.
Solution Approach 2:
The patent implements dynamics through continuous adjustment of transmission power based on real-time sensing information. The system dynamically monitors for eavesdroppers using sensing signals and adapts communication power levels in response to detected threats, creating a responsive security mechanism that evolves with the threat environment rather than using static power settings.
2Object-affected harmful factors
If transmission power is reduced to prevent eavesdropping, then communication security is improved, but communication reliability deteriorates
Solution Approach 1:
The patent applies local quality by implementing spatially selective power control where transmission power is reduced only in specific directions or beams where eavesdroppers are present, while maintaining full power in other directions where no threats are detected. This localized approach preserves communication reliability in secure regions while achieving security in threatened regions.
Solution Approach 2:
The patent implements dynamics through real-time adaptation of transmission power levels based on sensed eavesdropper positions. The system continuously adjusts power settings in response to changing threat conditions, ensuring that communication reliability is maintained when no eavesdroppers are present while security is enhanced when threats are detected, creating a dynamic balance between these two objectives.
