Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pseudo-random number generation methods are used, then the generated numbers exhibit statistical randomness, but the sequence is predetermined and can be cracked by reverse engineering
Solution Approach 1:
The patent replaces software-based pseudo-random number generation with a physical hardware system that uses electronic circuits and environmental noise to generate true random numbers. This substitution of mechanical/software systems with physical systems provides genuine unpredictability that cannot be reverse-engineered, resolving the security vulnerability of predetermined sequences while maintaining high randomness quality.
Solution Approach 2:
The patent introduces environmental noise as an intermediary source between the physical world and the random number generation process. By capturing ambient electromagnetic noise through antennas and processing it through electronic circuits, the system transforms unpredictable environmental phenomena into secure random number sequences, achieving both high randomness quality and security.
2Reliability
If hardware random number generation is implemented, then true randomness and security are achieved, but the device complexity increases
Solution Approach 1:
The patent designs the hardware random number generator with multi-functional capabilities that reduce overall system complexity. The electronic circuit performs multiple functions including noise signal amplification, processing, and random number generation within a single integrated system. The system can also operate in different modes (hardware-based or software-assisted) depending on security requirements, making the device adaptable and reducing the need for separate systems.
Solution Approach 2:
The patent combines multiple functional components into an integrated hardware system. The antenna, amplifier, processor, and output interface are merged into a unified random number generation device. This consolidation reduces the number of separate components and interfaces needed, thereby reducing overall system complexity while maintaining true random number generation capabilities.
3Measurement precision
If environmental noise is used as the source, then true random numbers are generated, but the signal quality may be insufficient without amplification
Solution Approach 1:
The patent applies partial amplification only to the extent necessary to achieve sufficient signal quality for random number generation. The amplifier boosts the weak environmental noise signal to an adequate level for processing, but not excessively, thereby minimizing energy consumption while still achieving the required randomness quality. The system uses just enough amplification to make the noise signal usable.

AI summary
Provided are an apparatus and method for generating a true random number, where a generated true random number is used for lotteries or sweepstakes. Since a random number generation edge node is made of a large number of transparent materials and placed in a public place to provide a live broadcast service for the public, and can support an information security auditing function, a high-credibility and auditable true random number can be visually generated. Since a plurality of random number generation edge nodes can be deployed in cities in different regions at the same time, power networks and communication networks are not shared. Intelligent software and hardware devices are used to generate random numbers automatically and rapidly, so true random numbers can be reliably, quickly, massively and neutrally generated for a long time. As a random number generation center node can provide a true random number seed generation service for all the public by means of a public interface, a random number generation service can be conveniently used at a low cost for a single user.
