    Security in decentralized databases
    (ХНУРЕ, 2019) Nazarov, A.; Kozel, N.; Gruzdo, I.; Kyrychenko, I.
    Blockchain is a distributed network that records digital transactions on a publicly accessible ledger. This paper explores whether blockchain technology is a suitable platform for the preservation of digital signatures and public/private key pairs. Conventional infrastructures use digital certificates, issued by certification authorities, to declare the authentication of key pairs and digital signatures. This paper suggests that the blockchain’s hash functions offer a better strategy for signature preservation than digital certificates. Compared to digital certificates, hashing provides better privacy and security. It is a form of authentication that does not require trust in a third-party authority, and the distributed nature of the blockchain network removes the problem of a single point of failure.

    Spatial Interpretation of the Notion of Relation and Its Application in the System of Artificial Intelligence
    (CEUR Workshop Proceedings, 2019) Proniuk, G.; Geseleva, N.; Kyrychenko, I.; Tereshchenko, G.
    This paper considers the point of view on relations that are interpreted as generalized spaces, in contrast to the classical definition of a relation as a subset of the Cartesian product of sets. The connection of generalized spaces with predicates and maps is also considered. Predicates accompanying generalized spaces, projection predicates are introduced. Possible interpretations of generalized spaces are presented. Looking at the attitude as a generalized space leads to the formulation of a number of interesting logical-mathematical problems and to the results that are promising for use in many areas of artificial intelligence.
