An international team of scientists has developed a system that generates random numbers a hundred times faster than modern technology. The development will pave the way for faster, cheaper and more secure data encryption in today’s world.
The random number generation system was developed by researchers from Nanyang Technological University of Singapore (NTU Singapore), Yale University, Trinity College Dublin and manufactured at NTU.
Random numbers are used for various purposes, such as generating data encryption keys and one-time passwords in day-to-day business (online banking and e-commerce) to keep them safe.
The new system uses a laser with a special hourglass-shaped cavity to generate patterns that are formed by light beams that reflect and interact with each other within the cavity. By reading the templates, the system generates many series of random numbers at the same time.
Keely that, like snowflakes, no two number sequences created by the system were the same due to the unpredictable nature of the reflection and interaction of light rays with each other in the cavity.
The laser used in the system is about one millimeter long. This is much less than most other lasers. It is also energy efficient and can work with any household outlet. It requires a current of only one ampere (1 A).
The laser system generates about 250 TB of random bits per second – a hundred times faster than modern computer generators. At this speed, the system only takes about 12 seconds to generate a collection of random numbers equivalent to the size of the information in the world’s largest library, the US Library of Congress. By the way, its fund exceeds 155 million copies of books in 470 languages.
In their study, published in the journal Science, the scientists confirmed the effectiveness of their random number generator. They proved that the generator created by NTU is faster and safer than existing comparable technologies. It will help protect user data in a world that increasingly uses online transactions.
Scientists are preparing to make the technology ready for practical use by incorporating a laser into a compact chip. It will generate random numbers that can be entered directly into the computer.
