Abstract
<p class="a"><span lang="EN-US">The ways of enhancement of productivity of generation of random sequences, derived from physical sources for information protection systems were substantiated. This is necessary because today there is a rapid growth of technological capabilities and of rate indicators of implementation of various information services and applications, required by community. One of the main issues of the safe use of these services is to ensure information security, which requires the use of effective highrate information protection systems and highperformance generation of random data sequences. In the course of conducting research with the aim of enhancing productivity, the features of conversion of actual noise processes, taking into consideration their nonstationarity and deviations from the probability distribution were analyzed. We proposed the ways to improve the methods of analogtodigital conversion with the optimization of the scale dynamic range quantization and the pitch of discretization of a noise process over time. With a view to aligning statistical characteristics, the possibility of using the processing methods that enhance its statistical quality with economy of highrate losses was explored. These are the method of sampling equally probable combinations (von Neumann – Elias –Ryabko – Matchikina) and the method of code processing (Santha – Vazirani) that provide an increased effectiveness due to code extension and involve conversion of the sequence: in the first method, with the use of equally probable combinations with rejection of unnecessary data; in the second method, without their rejection with the possibility of linear conversion. In order to optimize the conversion parameters at both stages of generation and to adapt these parameters to the peculiarities and changeability of characteristics of converted random processes, it was proposed to use feedbacks of converters’ outputs with previous conversion elements. </span></p><p class="a"><span lang="EN-US">The adjustment of the specified parameters can be made during the generation based on the results of statistical analysis of the outputs of conversion stages. The obtained results are quite important, since their implementation in modern information protection systems will enable guaranteeing information security and safe usage of applications of the modern information service and the introduction of new applications. </span></p>
