Washington DC [US]September 9 (ANI): A new type of random number generator for encryption developed at Linkouml;ping University in Sweden could make sharing safer, cheaper and less harmful to the environment.
The study’s authors believe that a new type of quantum communication will be possible thanks to the new technology.
Cyber security is becoming increasingly important in an increasingly interconnected world to secure not only the individual but also, for example, government infrastructure and financial institutions.
Additionally, individuals trying to protect information and hackers are always competing. Encryption is the most widely used method of information security. Information is thus digitally encrypted when we send e-mails, make online payments for bills and shop online.
A random number generator, which can either be computer code or the hardware itself, is used to encrypt the data. The information in the receiving side is encrypted and decrypted using keys generated by the random number generator.
Different random number generators offer different degrees of randomness and security. Hardware is a much safer choice because physical processes are responsible for regulating randomness. The hardware technology that produces the finest randomness, known as the Quantum Random Number Generator, or QRNG, is based on quantum processes.
“In cryptography, it is not only important that the numbers are random, but that you are the only one who knows them. With QRNGs, we can certify that a large amount of the generated bits are private and thus completely secure. And if the laws of quantum physics are true , it should be impossible to eavesdrop without the recipient finding out,” said Guilherme B Xavier, researcher at the Department of Electrical Engineering at Linkouml;ping University.
His research group together with researchers from the Department of Physics, Chemistry and Biology have created a new type of QRNG that can be used for encryption, betting and computer simulations.
The use of LEDs built from the crystal-like substance perovskite is a new aspect of QRNG developed by Linkouml;ping researchers.
Their random number generator is among the best made and performs admirably compared to similar products. It has the potential to be cheaper and more ecologically friendly due to the properties of perovskites.
Professor Feng Gao has been studying perovskites for more than ten years. He believes there is a chance to revolutionize, for example, optical instruments due to the recent invention of perovskite light-emitting diodes (PeLED).
“It is possible to use, for example, a traditional laser for QRNG, but it is expensive. If the technology is eventually to find its way into consumer electronics, it is important that the cost be kept down and that production be as environmentally friendly as possible. In addition, PeLEDs do not require much energy to drive, says Feng Gao.
“It is an advantage if electronic components that are to be used for sensitive data are manufactured in Sweden. If you buy a complete random generator set from another country, you cannot be sure that it is not monitored.” (ANI)
