Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3GPP 5G physical layer communication is used, then network connectivity is established, but security vulnerability increases in contested domains
Solution Approach 1:
The patent introduces an intermediary layer between the standard 3GPP 5G physical layer and the core network. This intermediary implements non-standard waveforms and signal processing techniques that mask the communication from conventional detection methods, thereby maintaining connectivity while reducing vulnerability to attackers using standard detection algorithms
Solution Approach 2:
The patent modifies key parameters of the physical layer communication, including waveform structure, modulation schemes, and signal timing, to deviate from standard 3GPP specifications. These parameter changes enable the system to maintain functional connectivity while becoming undetectable to conventional security threats that rely on standard protocol recognition
2Ease of operation
If RF environment communication is used, then wireless connectivity is achieved, but device protection is lost
Solution Approach 1:
The patent introduces signal processing intermediaries that transform standard RF communications into non-standard waveforms. These intermediaries maintain the ease of wireless operation while protecting devices by making their communications invisible to conventional RF detection and control mechanisms used by attackers
Solution Approach 2:
The patent creates modified copies of standard communication waveforms that replicate the functional characteristics needed for connectivity but alter the detectable characteristics. These copied and modified waveforms enable wireless operation while preventing attacker detection and control
3Adaptability or versatility
If standard network protocols are used, then interoperability is maintained, but detectability increases
Solution Approach 1:
The patent systematically changes physical layer parameters including waveform shape, modulation depth, and signal timing intervals while maintaining higher-layer protocol compatibility. This enables the system to maintain network interoperability while becoming undetectable to jammers that monitor for standard protocol signatures
