Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cryptographic message indicators are used in packet-based voice transmission, then secure communication is achieved, but bit errors in high bit error rate environments cause loss of cryptographic message indicators, disrupting decryption and synchronization
Solution Approach 1:
The patent applies preliminary action by pre-embedding the cryptographic message indicator into each data packet before transmission. This ensures that the indicator is readily available at the receiver end with each packet, eliminating the need to wait for separate indicator transmission and enabling immediate error correction and decryption operations.
Solution Approach 2:
The patent implements beforehand cushioning by incorporating error correction mechanisms directly into the cryptographic message indicator embedding process. The indicator is designed to withstand bit errors through redundancy and error detection/correction codes, providing a buffer against the harmful effects of high bit error rates in tactical environments before errors can disrupt decryption.
2Adaptability or versatility
If voice data is transmitted in packet form to enable seamless Internet connectivity, then connectivity is improved, but bit errors in tactical environments corrupt the cryptographic message indicators
Solution Approach 1:
The patent applies segmentation by dividing the voice data into multiple data packets for transmission, each containing its own embedded cryptographic message indicator. This segmentation allows the system to leverage Internet infrastructure for seamless connectivity while maintaining the integrity of cryptographic indicators within each individual packet, enabling independent error correction for each segment.
Solution Approach 2:
The patent uses the embedded cryptographic message indicator as an intermediary element within each data packet. This intermediary carries the necessary decryption information and error correction data, mediating between the transmitted voice data and the decryption process, ensuring that even in high bit error rate environments, the cryptographic integrity is maintained through the packet-based Internet infrastructure.
3Reliability
If code-combining is used to correct bit errors in cryptographic message indicators, then error correction capability is improved, but system complexity increases
Solution Approach 1:
The patent applies merging by combining multiple received data packets together through code-combining techniques. By accumulating and processing the embedded cryptographic message indicators from multiple packets, the system achieves improved error correction capability. This merging approach allows the receiver to reconstruct the original indicator information even when individual packets contain bit errors, balancing enhanced reliability with manageable system complexity.
