The problems and potentialities of reservation methods application in the field of informational security are considered. A concept of reservation of information system elements relative to threats of attack is introduced. Internal contradictions of reservation methods are revealed. The contradictions are shown to limit practical applicability of the methods to the complete problem of information protection, including confidentiality support, save access to the information, and data integrity. A method is proposed for reservation of information system elements with division of information processing procedure between the system elements.

Existing algorithms of intra-frame pixel brightness prediction are considered. The algorithms used in video compression standards H.265 and VP9 are analyzed, characteristics of the algorithms are studied, and recommendations on their application are formulated. It is shown that a fundamental problem in video compression is the referent frame redundancy, and reduction in spatial redundancy may be improved by increasing the efficiency of intra-frame prediction algorithms. Particular attention is paid to indicators such as quality, compression ratio and computational complexity of compression process. Improving the flexibility of the mechanism of prediction procedure selection is found to reduce significantly the computational expenses while retaining the prediction algorithm performance. An adaptive method of intra-frame prediction based on the algorithm introduced by H.265 standard is proposed. The method is invariant to variations in video scene properties and reduces significantly the computational cost at the expense of a slight decrease in the video series quality. Results of testing the developed method with the use of a number of video sequences from JCT-VC test set for the H.265 standard are presented.

Effective capacity of an information network consisting of homogeneous independent operators is estimated when the operators are subject to internal and external disturbing factors. The mathematical model used in the study is based on supposition of inverse relationship between the damage and the transmission capacity. For a given critical value of the network capacity, the risk level (a critical condition emergence probability) and corresponding damage volume are determined.
