A new way to protect against hacking threats from quantum computers was proposed by MTUCI scientists. For this, according to them, it is possible to use cryptographic schemes based on the theory of algebro-geometric codes. Currently, the research team is developing projects of new quantum-resistant national cryptography standards. The results are presented in a collection of papers from the 2022 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO) conference.
Today, specialists in the field of information security are faced with the problem of a quantum challenge – the emergence and spread of quantum computers. This makes it possible to implement in practice algorithms that easily break the ciphers used today based on public keys.
According to specialists from the Moscow Technical University of Communications and Informatics (MTUCI), the development of quantum-resistant, or post-quantum, cryptography systems will help prevent this. Such systems should be built on the basis of rather complex mathematical problems for which no effective solution algorithms have been found on computers, not only of the traditional, but also of the quantum type.
“We must be prepared that soon adopted cryptographic schemes may be defenseless against intruders. Fortunately, today, thanks to many years of research, we have solutions in our arsenal, including absolutely original ones – for building next-generation information security systems that are resistant to quantum threat.”, – explained the head of the post-quantum cryptography sector of the MTUCI Quantum Center Konstantin Pankov.
Based on the study of current international practice and its own scientific achievements, the scientist emphasized, the team is preparing drafts of new national standards to solve two basic problems of information security.
“Instead of the outdated Diffie-Hellman algorithms for generating a shared key and the GOST 34.10-2018 electronic signature standard, we for the first time proposed systems of the Classic McEliece type based on algebro-geometric codes, the parameters of which can be varied depending on the computing capabilities of the protected system and the required degree of information security. This is an indisputable advantage of the proposed approach and a big step forward in comparison with domestic and world practice.“, – said Pankov.
The new standards will be used on digital data platforms to meet the needs of citizens, businesses and authorities, which are an integral part of the country’s modern information infrastructure, the scientist added.
