Quantum technologies as a guarantee of privacy

Quantum technologies as a guarantee of privacy

Information is an expensive asset. Information leak can deprive money, position in society and even freedom. 650 million rubles were stolen from bank cards of Russians as a result of hacker attacks in 2016.

The article 75 of Arbitration Procedure Code of the Russian Federation was amended the same year. According to the amendment, a conversation with the mention of e-mail is recognized as official evidence in court, it is considered evidence in the United States since March 2011.

Cybercriminals also encroach on the right to privacy, regularly affecting celebrities. The world-famous ballerina Anastasia Volochkova suffered after her ex-boyfriend’s Vkontakte account was hijacked in November last year. The intruders posted her intimate photos online.

Everyone needs safe communication channels: medium and large business owners, Hollywood stars and actors, adults and children. That's why Tor Browser is among the top ten most downloaded browsers, and there is every chance Pavel Durov will launch the largest ICO in history due to Telegram's reputation as the safest instant messenger.

No wonder, cyber security specialists are constantly improving data protection algorithms, launching projects to search for and analyze “holes” in automated systems, and exploring the potential of blockchain technology.

Nevertheless, no matter how complex the mathematical algorithm is, there is always the risk of hacking it. Understanding this, scientists decided to change the approach to the problem, not the protection method. The reason for such a decision is knowledge in the field of quantum technologies.

Quantum telecommunications features

Information with restricted access must have three features: confidentiality, integrity and accessibility. If it is transmitted using quantum communication lines, integrity and accessibility are guaranteed. Why? It's all about the physical properties of quanta.

Information is transmitted sequentially with the help of binary code and is measured in bits in classical telecommunication. One bit can have one of two values: 0 or 1. In quantum communication, information is encoded in parallel with quantum bits (qubits), which can simultaneously be in the state 0 and 1.

The quantum state is very fragile, it breaks down easily. Thus, firstly, the outside observer does not know in which state the quantum is at the current moment, and secondly, when trying to find out, he will destroy it and cannot restore it.

As a result, any unauthorized interference in the quantum network will not go unnoticed, and the attacker will get nothing. In other words, the information will be integral and accessible only for the authorized participant of the network.

Quantum technologies will solve the problem of data accumulation as well. According to International Data Corporation (IDC) report, the volume of all data in the world will occupy 40 zettabytes, or 5500 GB per each inhabitant of the Earth by 2020. Mankind does not have enough computing power to handle this Big Data, but a universal 50 kbit quantum computer can solve this problem.

Who “builds” quantum communication

In Russia, both research institutions and telecom operators pay close attention to the quantum communication lines. ITMO University and Moscow State University, as well as the Russian Quantum Center and the SMARTS, are working on their own projects.

It is important to have domestic developments in the field of data security both from the point of view of security and economic benefit. Some foreign companies offer equipment for generating and sending a quantum key for $100K. Russian company Quantum Technologies, based on ITMO University, is working on similar devices.

SMARTS received a 160 million rubles grant from the Ministry of Education and Science to develop a data center management system, which will use the quantum technology to protect communication lines, excluding the possibility of cyberattacks.

Representatives of these institutions and companies will hold a thematic panel discussion at the Quantum Technology Conference in Moscow on March 1. The commercial director of JSC SMARTS Igor Nalivaiko will talk about the telecom infrastructure with quantum telecommunications, and Head at the Quantum information laboratory of the International Institute of Photonics and Optoinformatics of the ITMO University Artur Gleim will talk on the use of quantum communication lines under telecommunications standards.
