Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weak Random Number Generators (RNGs) are used in IoT devices, then device complexity is reduced, but security reliability deteriorates making devices vulnerable to cyberattacks
Solution Approach 1:
The TRMFF circuit generates true random numbers using intrinsic metastable phenomena and thermal noise within the flip-flop circuit itself, without requiring external entropy sources or complex hardware. The circuit serves its own randomness generation needs through its natural physical behavior during metastable transitions
Solution Approach 2:
The patent replaces traditional mechanical or software-based RNG mechanisms with a purely electronic/metastable physical phenomenon-based system. The TRMFF utilizes quantum-level thermal noise and metastable state transitions to generate randomness, substituting complex mechanical or algorithmic systems with a simple electronic circuit
2Reliability
If traditional RNGs are used in IoT devices, then ease of manufacture is improved, but security vulnerability increases due to predictable output patterns
Solution Approach 1:
The patent changes the fundamental operating parameter of the flip-flop from stable state to metastable state. By controlling the flip-flop to operate in the metastable region and measuring the time to resolve to a stable state, the system generates cryptographically secure random numbers based on the inherent unpredictability of metastable transitions
Solution Approach 2:
The TRMFF circuit generates true random numbers using intrinsic metastable phenomena and thermal noise within the flip-flop circuit itself, without requiring external entropy sources or complex hardware.

3Manufacturing precision
If simple RNG implementations are used, then device complexity is reduced, but output randomness quality deteriorates leading to biased distribution of logical ones and zeros
Solution Approach 1:
The patent incorporates a bias detection and correction mechanism that monitors the output distribution of logical ones and zeros from the TRMFF circuit. When bias is detected, the system applies corrective transformations to ensure uniform distribution, maintaining high randomness quality through automated feedback control
Solution Approach 2:
The patent changes the fundamental operating parameter of the flip-flop from stable state to metastable state. By controlling the flip-flop to operate in the metastable region and measuring the time to resolve to a stable state, the system generates cryptographically secure random numbers based on the inherent unpredictability of metastable transitions

Data Source
AI summary
A true random metastable flip-flop (TRMFF) compiler generates an electrical architecture for a TRMFF chain. The compiler selects components for the TRMFF chain from a library of standard cells and logically connects these components in accordance with a primitive polynomial to generate the electrical architecture. The TRMFF chain provides a sequence of random numbers from one or more physical processes in accordance with the primitive polynomial. During operation, one or more microscopic phenomena inside and/or outside of the TRMFF chain can cause one or more low-level, statistically random entropy noise signals to be present within the TRMFF chain. The TRMFF chain advantageously utilizes the one or more low-level, statistically random entropy noise signals to provide the sequence of random numbers.
