Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic scanning or searching of RF signals is implemented, then communication system productivity is improved, but security against adversarial attacks deteriorates
Solution Approach 1:
The patent applies preliminary action by conducting adversarial attacks during the training phase of the neural network before actual communication occurs. The measurement device generates adversarial examples and feeds them into the neural network to pre-train it to recognize and resist such attacks, ensuring that when real RF signals are scanned automatically, the system already has defenses in place.
Solution Approach 2:
The patent introduces an intermediary measurement device that acts as a mediator between the communication system and adversarial attacks. This measurement device generates adversarial examples, manages the training process, and evaluates resistance without being part of the core communication system, allowing secure testing without compromising operational security.
2Reliability
If neural network training is performed before transmission, then communication reliability is improved, but time consumption increases
Solution Approach 1:
The patent applies preliminary action by performing neural network training before actual communication transmission. The measurement device prepares adversarial examples and trains the neural network in advance, so that when real communication occurs, the system is already optimized for reliable signal recognition and resistance to adversarial attacks.
Solution Approach 2:
The patent ensures continuity of useful action by making the neural network training an ongoing process that continues as long as communication systems operate. The measurement device continuously generates new adversarial examples and updates the neural network, ensuring that training is not a one-time event but a continuous improvement process that maintains reliability over time.
3Measurement precision
If measurement device generates and manipulates RF interference signals, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the measurement device to perform multiple functions: generating RF signals, creating adversarial examples, manipulating interference signals, and measuring resistance. This multi-functional design consolidates what would otherwise require separate devices into a single integrated system, managing complexity through functional consolidation rather than multiplication.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting RF signal parameters (frequency, amplitude, modulation) based on the measurement requirements and the specific communication system being tested. The measurement device adapts these parameters to optimize the adversarial attack effectiveness and measurement precision for different scenarios without requiring complex hardware reconfiguration.
4Measurement precision
If adversarial attacks are carried out using RF signals, then measurement accuracy is improved, but harmful factors increase
Solution Approach 1:
The patent applies the blessing in disguise principle by converting potentially harmful RF interference signals into beneficial training data. The measurement device generates adversarial RF signals that would normally be considered harmful interference, but instead uses them to train the neural network to recognize and resist such attacks, turning the harmful factor into a valuable learning resource.
Solution Approach 2:
The patent introduces an intermediary measurement device that acts as a mediator between the harmful RF interference and the communication system. This device generates and controls the adversarial RF signals, ensuring they are used only for measurement and training purposes, and prevents them from causing actual harm to the system being tested.
