GENERALIZED MODEL OF INFORMATION PROTECTION PROCESS IN AUDIOVISUAL CONTENT DISTRIBUTION NETWORKS

The most important indicators of the effectiveness of content protection systems are indicators of the achieved security level, i.e. functional properties of security. These indicators are: confidentiality, integrity, availability. Each of the indicators of the functional properties of content security is distributed according to the methods of ensuring and the degree of its achievement. A significant drawback of such indicators is that they are qualitative. This significantly narrows the scope of their use and makes it impossible to use them in mathematical expressions for optimizing the parameters of protection means, obtaining quantitative estimates of the performance quality of the protection system or its components, etc. The work offers a number of quantitative indicators, which, depending on the purpose, can be probabilistic and temporal. Calculation of such indicators makes it possible to assess the degree of ensuring the functional properties of information security or the possible degree of ensuring the functional properties of protected information.
