His research is based on quantum technology and its extreme security. There is a maxim that almost all those responsible for cybersecurity continuously repeat: “If you are connected, you can hack.
“Almost all, because researchers from the University of Bristol (United Kingdom) have developed an Internet network that is practically one hundred percent secure. “The largest quantum network of its kind,” they say.
Among its advances is a “completely secure” communication free from any threat of interception of any message on this platform. “Our solution is scalable, relatively inexpensive, and most important of all, impregnable.
That means that it is an exciting rule change and paves the way for much faster development and widespread deployment of this technology, “says Siddarth Joshi, member of the Quantum Engineering Technology Laboratory at the University of Bristol, the publication Unilad.
Currently, the internet is riddled with codes that protect the information. However, cybercriminals are always more advanced. During the Covid-19 pandemic, the number of attacks on the Internet has grown.
Google’s surveillance services detected, in April alone, 18 million daily attempts at cyberattacks. For its part, Microsoft sees 60,000 messages with malicious files or links linked to the SARS-CoV-2 virus every day.
The Bristol researchers are committed to the need to find an alternative and have set their sights on quantum technology to make the information shared on the Internet impregnable.
Physicists have already developed a type of secure encryption called quantum key distribution that transmits light particles, known as photons.
Thanks to this technology, two users can share a secret key to encrypt and decrypt the information without being intercepted.
“Until now, efforts to expand the internet have involved a vast infrastructure and system that requires the creation of another transmitter and receiver for each additional user,” says the Bristol researcher.
In their process designed based on quantum technology, instead of making connections, the team built a system in which each user only had one fiberglass connected to a source of quantum entanglement, thus increasing safety.
