Modern man hangs out on the Internet, listen to radio and watch movies from the Internet, read electronic books and newspapers, books flights and hotels through the Internet, makes electronic transactions, etc. The cyber security and privacy of people are constantly threatened and adversaries constantly found new means of attacking, eavesdropping, communicating and coordinating their malicious actions. This project targets several different aspects of security and reliability in data communication. Two activities are associated with digital steganography, and their goal is discovering of new covert channels in the new web transfer protocols, such as HTTP/2 and QUIC, as well as using new anti-steganographic techniques for digital images in order to prevent terrorists to use them for hidden communication. The ultimate goal is to obtain a modular tool that would use the cloud storage services and web applications that provide a public service for images. Two other activities are related to cryptography, and include the development of optimal 8x8 S-boxes from small quasigroups of order 4 or 8, or from binary quasi-cyclic codes; development of an E-voting system using Bitcoin technology; development of Hill cipher cryptosystem with CSPRNG, and parallel realization of some cryptographic algorithms related to cryptographic measures for S-boxes. One activity involves the analysis and processing of data obtained by testing computer and network security, by using algorithms from artificial intelligence. Regarding reliability, algorithm design is planned, for finding a minimal path and cut vectors for multi-state networks.
