Prygara M. Secure system of technical support of processes of remote expression of will

The dissertation is devoted to the technical protection of information within the remote voting system (RVS), which guarantees secrecy of votes and ensures freedom of expression of will in conditions of administrative pressure. "Weaknesses" are identified in the protection of existing RVS, including specific threats to information, the lack of counteraction which undermines the trust of citizens in its "honest" work. The possibilities and ways of neutralizing these "weaknesses" are determined. The model of the RVS was constructed, which, by introducing an unlimited number of users with access rights to reviewing all files and processes on the server, but without the right of any modification, was able to detect all violations of the security policy regarding the integrity of the results of the expression of will and the confidentiality of votes in conditions of distrust to all, without exception, persons involved in the development, creation and servicing of the RVS. An improved method of secure data exchange over the Internet is proposed, which, due to the use of random bit sequences and the coherent application of the Vername cipher and the Diffie-Hellman algorithm with parameters that guarantee the stable data protection, and, due to the preservation of the distance of unity according to K. Shannon, provide a formally grounded impossibility of violation confidentiality of data in the communication channel.
