Makutonina L. Methods and models of cryptographic transformations with proven resistance, which is based on an identity and algebraic lattices

In the thesis proposed and proved methods of assessment methods directional hybrid encryption identifier for a set of conditional and unconditional criteria and indicators for assessing the use of which allows you to assess the stability, both in terms of individual attacks, and by a combined criterion.The dissertation is devoted to solving important scientific and technical task - the development of the combined method Identity-Based Encryption from Lattices and its programming model, for use in cryptographic mechanisms and protocols, which differs from the current that models based on algebraic lattice can bring exponential complexity of cryptanalysis method of full-disclosure, and improve the performance of cryptographic conversion to 2-3 orders of magnitude. Results of dissertations were introduced in educational process of the Kharkiv National University of Radio Electronics and AT "Institute of Information technologies".
