Engineering Physics Annotation << Back ON THE CALCULATION AND ATTRIBUTION OF QUANTITATIVE ASSESSMENTS OF THE DEGREES OF TRUST TO THE LEVELS OF TRUST IN SOFTWARE PRODUCTS OF OPERATING ENVIRONMENTS OF AUTOMATED INFORMATION SYSTEMS S.G. SINEV, A.A. ROMANOV The level of power of attorney is studied as a complex concept that combines the components of ensuring information security and manufacturability. These components are evaluated by appropriate degrees of confidence. A formal formulation is presented and the problem of calculating the upper and lower bounds of verbally specified intervals of power of attorney is solved, taking into account their importance. The boundary values of the degrees of trust for these intervals are determined by evaluating the composite and partial criteria of trust and their significance. Quantitative estimates of the degrees of trust of the components of information security and the manufacturability of software products of operating environments are calculated, which correspond to one of the intervals of the power of attorney. A quantitative assessment of the degree of trust in manufacturability can be used to assess the achieved technological level of development and production of software products. Keywords: the interval of the power of attorney, the level of the power of attorney, the degree of trust, information security, technological independence, trust criteria, expert assessments.
