Quantum Random Number Generator Revolutionizes Cybersecurity

Scientists Develop New Quantum Random Number Generator for Safer Data Encryption

Scientists from the University of Linceping, 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 opens the way to a new type of quantum communication, according to researchers.

In the rapidly growing digital world, cybersecurity is becoming increasingly important, particularly to protect national infrastructure and banking systems. Encryption remains the primary strategy for ensuring data security, whether it’s sending emails, online shopping, or paying bills.

Different random number generators provide varying levels of randomness and security. The most secure method is the hardware-based quantum random number generator (QRNG), which relies on quantum phenomena.

“In cryptography, it is not only important for the numbers to be random, but also for you to be sure of them. With the use of QRNG, we can ensure that a large number of generated bits are private and, therefore, completely safe,” says Guillerme B. Javier, a researcher from the University of Lynchoping.

The unique feature of the new QRNG developed by scientists from the University of Linceping is the utilization of LEDs based on a crystalline material called perovskite. This new random number generator has the potential to be cost-effective and environmentally friendly due to the properties of perovskites.

Professor Feng Gao, who has been studying perovskites for over ten years, believes that the recent development of perovskite LEDs could lead to a revolution in the field of optical devices.

The next step in the development will involve improving the perovskite material by making it lead-free and increasing its lifespan, which currently stands at 22 days. According to Guillerme B. Havier, their new QRNG could be implemented in the field of cybersecurity within five years.
