A novel arc discharge light-induced true random number generator (TRNG) uses a unique photodetector to create highly random bits. This hardware security solution offers secure password systems and artificial X-ray image generation.
Area of Science:
- Hardware security
- Random number generation
Background:
- True random number generators (TRNGs) are crucial for hardware security.
- Existing TRNGs explore diverse physical phenomena for randomness.
- The need for robust and efficient TRNGs persists.
Purpose of the Study:
- Introduce a novel arc discharge light-induced TRNG (ALTRNG).
- Investigate wavelength-dependent photocurrent generation for randomness.
- Validate the randomness of generated bits using NIST standards.
Main Methods:
- Utilized arc discharge irradiation and a bipolar photo-responsive photodetector (BPPD).
- Exploited the BPPD's distinct photocurrent responses to deep-ultraviolet (DUV) and blue light.
- Employed National Institute of Standards and Technology (NIST) 15 tests for validation.
Main Results:
- The ALTRNG produced highly random bits with proven unpredictability, uniform distribution, and stability.
- Demonstrated distinct photocurrent generation under arc discharge illumination.
- Achieved a readout circuit speed of 2 kbps for wireless transmission.
Conclusions:
- The ALTRNG is a viable hardware security solution for generating true random numbers.
- Wireless random number transmission is feasible, enabling applications like secure password systems.
- Potential applications include secure communication and artificial X-ray image generation.

Biot-Savart Law: Problem-Solving
Consider a mobile phone battery bank as a source of steady current, which flows through the wire connected between the two. What is the magnitude of the magnetic field created by this current at a field point P?
To estimate the magnitude of the total magnetic field, we first consider a small current element of length dl, at a distance r from the field point. Now the following...
