Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software protection (firewall/antivirus) is used to detect abnormal data, then known risks can be filtered, but unknown threats cannot be detected and privacy is compromised
Solution Approach 1:
The patent replaces traditional software-based security mechanisms (firewalls, antivirus) with quantum cryptographic mechanisms. Specifically, it uses quantum key distribution to establish secure communication channels, where security is guaranteed by quantum mechanical principles rather than software detection algorithms. This substitution enables detection and prevention of unknown threats through quantum entanglement and no-cloning theorems, while preserving user privacy through quantum protocol design.
2Reliability
If software protection is used to detect attacked data, then passive defense can be taken, but active defense cannot be implemented
Solution Approach 1:
The patent implements preliminary action by establishing quantum secure communication channels before data transmission occurs. The quantum key distribution protocol generates and distributes encryption keys through quantum-secured channels prior to the actual data exchange, enabling active defense against potential threats. This preliminary securing of the communication channel allows the system to proactively prevent attacks rather than merely detecting them after occurrence.
3Reliability
If software protection requires access to user data for detection, then data can be scanned for attacks, but privacy cannot be protected
Solution Approach 1:
The patent extracts the security verification function from the data content itself. Instead of scanning user data for attack patterns, the system uses quantum cryptographic protocols to verify the security of the communication channel. The quantum key distribution process separates the security verification mechanism from the actual data being transmitted, allowing attack detection capability to be maintained through quantum protocol validation while user privacy is preserved since the content of transmitted data never needs to be accessed or scanned.

AI summary
The present application provides a universal quantum secure device and methods of sending and receiving data. A quantum encryption and decryption module can realize quantum encryption and decryption of data requiring quantum encryption service, thereby ensuring that data sent and received by the universal quantum secure device from a conventional network are transmitted in ciphertext form. An isolation module can realize isolation between the communication module and each of the quantum encryption and decryption module and a privacy module, so that security of the privacy module and security of the quantum encryption and decryption module are protected from being affected by data received by the communication module from external network. Since the privacy module does not communicate with external network, and encryption and decryption of the data can only be carried out in the quantum encryption and decryption module of the universal quantum secure device, improving data security.
