Prospective Areas of Research in the Development of Post- Quantum Cryptography

Abstract

Critical questions about the need to prepare both international and domestic information infrastructure for the emergence of post-quantum mechanisms of cryptanalysis of critical information on the corresponding computing systems are considered. This requires taking into account the experience of the international community in developing and testing a series of post-quantum standards in the field of cryptographic protection of key information. At the same time, it is very important to take into account the following aspects that the Ukrainian standardized system insists on the use of time-tested encryption mechanisms: when the longterm studies of connectivity will not be detected in this mechanism. Except for the NTRU scheme based on McAlice’s theory and other encoding schemes, post-quantum cryptography has a history of up to 5 years. To some extent, NIST has been rushing to implement postquantum encryption technology (for example, a memorandum issued by the U.S. National Security Agency in 2015 provided U.S. developers with encryption to protect important information that has not yet been included in its products. Introduction of information encryption technology. Algorithms based on elliptical curve operations avoid the implementation of these algorithms to save resources with the proposed transition to postquantum algorithms), which forces us to carefully test new standards developed in the procedures of the organization to avoid using standards for the generation of pseudo-random numbers. Many researchers objected, but pointed to obvious loopholes, so the standard needs to be revoked. Proceeding from this it is obvious that the moment of transition to postquantum cryptography will require fundamental reorganization of the whole basic infrastructure of information protection, all methods of information protection using asymmetric cryptographic algorithms, especially the infrastructure of an authentication center. Taking into account the cost of these events, one should make a cautious decision about the transition to post-quantum cryptography based on accurate forecasts of the development of post-quantum computing system functions. Based on the above-mentioned research, we can confidently say that the global IT community is actively preparing for significant changes with the advent of the post-quantum era.
