Random Number Generation Device and Method

Device for generating random numbers using electrical signals based on object surface roughness

This technology relates to a random number generation device and method, comprising an electrical signal generation unit that generates electrical signals dependent on the surface roughness of an object, and a random number generation unit that generates random numbers based on these signals.

Existing random number generation methods are algorithm-based, leading to predictability and thus limited security in security and encryption applications.

To address this, this technology generates random numbers using electrical signals derived from physically unique surface roughness, thereby providing high-quality physical random numbers that are difficult to predict.
