Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pseudo-random number-based encryption keys are used for secure communication, then device complexity is reduced and ease of manufacture is improved, but security reliability deteriorates due to vulnerability to hacking and pattern analysis
Solution Approach 1:
The patent changes the fundamental parameter of random number generation from classical pseudo-random algorithms to quantum random number generation. This parameter change transforms the security basis from computational complexity to quantum physical laws, achieving unconditionally secure encryption keys that are immune to pattern analysis and hacking while maintaining practical device implementation through quantum encryption chips.
Solution Approach 2:
The patent replaces the mechanical/computational system of pseudo-random number generation with a quantum physical system. By using quantum phenomena (such as quantum tunneling or photon detection) to generate truly random numbers, the system achieves fundamental security improvements over classical computational methods, making the encryption vulnerable only to quantum attacks rather than classical computational analysis.
2Reliability
If quantum-random-number-based quantum encryption chips are deployed, then security reliability is significantly improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent extracts the quantum random number generation function into a separate, dedicated quantum encryption chip module. This modular extraction allows the complex quantum functionality to be isolated and manufactured as a standalone component, which can then be integrated into various secure communication devices, thereby reducing the overall manufacturing complexity compared to building entire quantum systems from scratch in each device.
Solution Approach 2:
The quantum encryption chip is designed as a universal module that can be applied across multiple device types and communication protocols. By creating a multi-functional quantum security module that works with different terminals (mobile phones, IoT devices, computers), the patent reduces manufacturing complexity through standardization and enables widespread deployment without requiring separate quantum implementations for each device type.
3Reliability
If end-to-end quantum secure communication channels are established between terminals, then security against eavesdropping is improved, but communication system complexity increases
Solution Approach 1:
The patent introduces a quantum encryption chip as an intermediary component between the terminal and the communication network. This intermediary handles the complex quantum key generation and encryption operations, allowing the terminal itself to remain relatively simple while still achieving end-to-end quantum secure communication. The chip mediates between classical communication interfaces and quantum security requirements.
Solution Approach 2:
The patent segments the secure communication system into distinct functional layers: terminal devices, quantum encryption chips, communication networks, and management servers. Each segment handles specific tasks (terminal for user interaction, chip for quantum key generation, network for transmission, server for key management), reducing overall system complexity by distributing functions across multiple independent components rather than requiring complex integration in each device.

AI summary
A method of providing a secure communication service using a secure communication device equipped with a quantum-random-number-based encryption chip. The method includes: in response to a first user terminal executing a secure communication device service app for secure communication and inputting a personal information number (PIN) or pattern, performing device authentication between a first user secure communication device and the first user terminal and then performing remote authentication between the first user terminal and a management server; in response to user authentication being completed, generating a quantum secret key a by a quantum encryption chip of the first user secure communication device and transmitting a quantum public key A to a second user secure communication device; and creating, by the first user secure communication device, a speech secure communication channel for communication with the second user secure communication device by inducing and storing the quantum encryption key.
