An international team of scientists from the University of St. Andrews (Scotland), the King Abdullah University of Science and Technology (Saudi Arabia) and the Center for Alternative Scientific Processes (USA) created and presented the perfect encryption system, which is absolutely impossible to crack.
Scientists claim that they have developed a cryptographic system that cannot be cracked even with the help of quantum computers.
“Protecting confidential data is a major worldwide challenge. Classical cryptography is fast and scalable, but is broken by quantum algorithms. Quantum cryptography is unclonable, but requires quantum installations that are more expensive, slower, and less scalable than classical optical networks. We show a perfect secrecy cryptography in classical optical channels”, — say scientists from the international team.
A prototype of a silicon chip created by scientists uses the classical laws of physics, including chaos theory and the second law of thermodynamics, to achieve “perfect secrecy”.
The generated cryptographic keys that are used to unlock each message are never stored or transmitted with data packets. The technology uses correlated chaotic wave packets mixed in low-cost and CMOS-compatible silicon chips. A perfect secrecy cryptography, known as a one-time pad (OTP) was invented at the time of the telegraph and then patented by Vernam. The Vernam cipher encodes the message via a bitwise XOR operation with a random key that is as long as the text to be transmitted, never reused in whole or in part, and kept secret.
Later proved that this scheme, properly implemented, is unbreakable and does not offer any information to an attacker, except the maximum length of the message.
“We developed a physical realization of the OTP that is compatible with the existing optical communication infrastructure and offers unconditional security in the key distribution”, — report researchers of the international team.
According to the researchers, even an attacker with “unlimited” technological power or access to the system with the ability to copy microcircuits will not be able to crack encryption.
Professor Andrea di Falco reported that the method allows transferring information between users with light speed around the world and at any distance. To implement this technology, an inexpensive optical chip is sufficient.
However, no matter how securely your messages are encrypted, still avoid clicking on the sent photo of Taylor Swift and Scarlett Johansson. For example, in the former can hide its activities the MyKingz botnet.
