Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-channel transmission method is used, then the device complexity is low, but the security of secret key transmission is insufficient
Solution Approach 1:
The patent divides the transmission channel into multiple independent wavebands (first waveband, second waveband, third waveband, etc.), each carrying encrypted secret key information. This segmentation allows the system to transmit security-critical data through multiple separate channels, ensuring that compromise of one channel does not endanger the entire system. The encrypting unit encrypts the secret key before transmission, and the detecting unit receives and decrypts signals from multiple wavebands to verify consistency.
Solution Approach 2:
The patent introduces an encrypting unit as an intermediary component between the signal source and transmission channels. This encrypting unit processes the secret key information before it enters the transmission medium, ensuring that even if multiple channels are intercepted, the actual secret key remains protected. The intermediary encryption layer adds a critical security barrier that prevents direct access to the sensitive information.
2Object-affected harmful factors
If multiple wavebands are used for transmission, then the crack difficulty increases, but the device complexity increases
Solution Approach 1:
The patent transitions from single-channel transmission to multi-dimensional transmission by utilizing multiple wavebands (frequency dimensions). Each waveband represents a different dimensional channel for transmitting the same encrypted secret key information. This dimensional expansion makes interception and cracking significantly more difficult, as attackers would need to compromise multiple independent frequency channels simultaneously. The multi-band detecting unit corresponds to receive and process signals across these different dimensional channels.
3Reliability
If encryption is applied to digital signals, then the security performance is improved, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary encryption action to the secret key information before it is transmitted through the multiple wavebands. The encrypting unit performs the encryption operation in advance, converting the plaintext secret key into ciphertext. This preliminary cryptographic processing ensures that the information is secured before entering the complex multi-channel transmission environment, reducing the need for additional security measures during transmission and reception.
