Perovskite-based QRNG promises a new level of protection.
Scientists from Linköping University, Sweden, have developed a new type of random number generator for encryption, which makes the exchange of digital information safer, cheaper and environmentally friendly. This innovation, according to the researchers, opens the way to a new type of quantum communication.
In a rapidly growing digital world, cybersecurity is becoming increasingly important, primarily for protecting national infrastructure and banking systems. Encryption remains the primary strategy for ensuring data security, whether it's when sending emails, shopping online, or paying bills.
Different random number generators provide different levels of randomness and therefore security. The most secure method is a hardware method based on quantum phenomena - the so-called quantum random number generator (QRNG).
"In cryptography, it is not only important that the numbers are random, but also that only you know about them. With QRNG, we can claim that a large number of generated bits are private and therefore completely secure, " says Guilherme B. Javier, a researcher at Linköping University.
A special feature of the new QRNG, developed by scientists from Linköping University, is the use of LEDs based on a crystalline material-perovskite. Thanks to the properties of perovskites, the new random number generator has the potential to be cheap and environmentally friendly.
Professor Feng Gao, who has been studying perovskites for more than a decade, believes that the recent development of perovskite-based LEDs could lead to a revolution in optical devices.
The next stage of development will be to improve the material to make perovskite lead-free and increase its service life, which currently stands at 22 days. According to Guilherme B. Javier, their new QRNG can appear in the field of cybersecurity within five years.
