Random numbers are one of the most important issues in the field of security and cryptography. The speed at which these random numbers are generated is of particular importance that scientists have now succeeded in building a laser system that is capable of generating random numbers at a much higher speed than active systems.
Security has always been a vital issue in the world, but it became even more important as many activities became electronic. These days, however, as computers become more powerful, hackers can more easily attack systems and steal users’ vital information. In the meantime, cryptography is one of the most common and powerful ways to prevent this from happening.
In the field of cryptography and cryptographic keys, random numbers are one of the most important issues that determine the level of security. Then In fact, in the field of cryptography, the more random and unpredictable the key, the harder it is to break, and in other words, the higher the security it provides.
Over the years, various methods have been developed to generate random numbers. One of the simplest and easiest ways is to roll a coin or dice. In modern cryptography, however, we seek to be able to generate large-scale, large-scale, high-speed random numbers in bits or numbers.
One method of generating random numbers has been the use of laser-based systems. Lasers are made of small quantum photons that behave erratically and unpredictably. However, the random oscillations of these particles lead to the production of a laser beam that can be detected by a computer.
The problem with this method so far has been that the systems based on this method were not very numerous and on the other hand did not have a high speed in generating random numbers.
Also, these systems were not able to generate numbers simultaneously from one beam.
Scientists have now succeeded in using chip-scale lasers to generate random numbers at 100 times the speed of current systems. The new project will be led by Professor of Applied Physics at Yale University, Hugh Cao. He points out in part that the physical systems that exist in this field and are used to generate random numbers are not very fast.
These systems, on the other hand, are sequential, meaning that they can only generate one bit stream and are not capable of generating multiple streams simultaneously.
Hence, due to the sequence and low speed, they slowly generate random numbers. This slowness comes at a time when systems’ processing power is increasing dramatically, and data security needs to be much faster to generate random numbers.
The system designed by Professor Hugh Cao is practically a response to this need. The team has designed a small but professional laser that looks like an hourglass.
With the laser beam, the light bounces in between the hourglasses, and this oscillation in the quantum particle density is recorded with a high-speed camera. This is where the computer converts these fluctuations into random numbers.
Interestingly, for the first time in these random number generation systems, a laser hole has been considered in the new design, which is responsible for amplifying light waves. Due to this feature, random bits are generated in parallel.
The new system is capable of generating 250 terabits of random bits per second, which is twice as fast as the current fastest system.
Achieving such systems requires very small chips, chips that include lasers and photodetectors. Of course, there are many companies that are currently researching and working on these issues, and will likely come up with significant technologies in the near future.
