Year: 2024
Type: article
Abstract: Today, hashing methods are very actively used in modern information and communication systems to check the integrity of these information resources. However, it should be noted that the main disadvantage of these methods is high algorithmic complexity and, as a result, increased requirements for computing power. This is due to the fact that the process of forming a typical hash function involves a large number of complex mathematical constructions. Therefore, it is urgent to search for new approaches to the formation of hash functions, in the conditions of ensuring the appropriate properties that hash functions demonstrate. The operational center for responding to cyber incidents of the State Center for Cyber Protection of the State Intelligence Service published a report on the results of the vulnerability detection and response system, in which it was found that the activity of hacker groups in spreading malicious software increased significantly this year. The purpose of this study was to justify recommendations for improving information security in ensuring the integrity of the information resource. An evaluation of the variant of the construction of the hash function calculation logic scheme and the construction of a new function was carried out by conducting a speed analysis with a comparison of typical hash functions. The speed of processing the incoming message has been improved by introducing a parallelization method to the structure of the “Kupyna” hash function algorithm. This method meets the modern requirements of information security and makes it possible to increase resistance to the appropriation of information by the enemy. After calculating the speed based on information security recommendations, the hash function “Kupyna” meets the requirements of modern warfare. Then, with these conditions, the data transmission system meets the requirements that will be needed in a difficult environment. The next step of research is to increase the stability of the integrity of the information resource by introducing a compression function into the algorithm to increase information security in the information and communication network of the Air Force.
