Application of cryptographic methods to blockchain technology to increase data reliability

Abstract

Controlling technological processes using digital technologies affects minimizing costs, both in terms of time and economy, and consequently dramatically increases labor productivity. Optimization of automation of controlled processes based on digital technologies is one of the main directions of development of information technologies. Increasing the dependability of the data of controlled mechanisms is one of the main directions of research today. In the modern era of information and globalization, a sharp growth in the set of data leads to the evolution of processes for storing, processing, and transferring data in network technologies. As a result, the problem of data reliability in these networked systems is growing. Today, improving data reliability based on information security is an urgent problem. Blockchain technology, which appeared at the beginning of this century, represents a new approach to securing data in networked systems. The priority of blockchain technology is the presence of a special cryptographic chain in its structure. This study addressed the issue of improving cryptographic techniques and cryptographic strength analysis based on blockchain mechanisms. The modern RSA6 cryptographic method has been improved based on the blockchain engine and the D_ RSA6 algorithm has been developed. The crypto security of the D_RSA6 algorithm has been analyzed and experimented with. It is proved that the developed algorithm D_RSA6 is the optimal method for increasing the reliability of network systems data. The algorithm, based on the integration of blockchain technology with cryptographic methods, leads to a 2-fold increase in cryptocurrency tolerance. This allows you to increase the reliability of the data.
