MULTI-CRITERIAL ASSESSMENT OF ALTERNATIVES IN DESIGNING OF TWO-FACTOR AUTHENTICATION OF USERS IN INFORMATION PROTECTION SYSTEMS

Abstract

The work is devoted to solving the urgent scientific and technical problem of increasing the level of information security by designing two-factor authentication of user subjects in information security systems with a multi-criteria comparison of the components of two-factor authentication. Based on the analysis of the authentication methods of user subjects that are used in the protection of information, a lot of the most used methods and their areas of application were substantiated. The purpose of the study is a multi-criteria assessment of alternative methods of authentication of user subjects during designing two-factor authentication in information security systems. Results. The paper analyzes methods of authentication of user subjects, including perspective methods of biometric authentication in order to build two-factor authentication. For multicriteria comparison of authentication methods, the use of the hierarchy analysis method (HAM) is justified, which implements the hierarchical structure of the comparison of alternatives. At each level of the HAM, the corresponding matrices of paired comparisons are built, the elements of which are expert assessments. A system of local criteria for comparing alternatives and the corresponding matrices of paired comparisons as well as a matrix of paired comparisons of local criteria and a procedure for calculating the global criterion have been developed.
