Анализ симметричных криптосистем

Анализ симметричных криптосистем

Abstract

Рассматриваются основные аспекты применения современных методов криптоанализа для оценки стойкости симметричных блочных алгоритмов шифрования. В том числе, рассмотрены такие методы анализа как линейный, дифференциальный, алгебраический анализы, слайдовая атака. Также рассмотрены различные подходы к анализу стандарта AES. Дано определение Парадоксу дней рождений и объяснена его роль в решении задач защиты информации. При рассмотрении подходов к анализу современных симметричных криптосистем отдельное внимание уделено вопросам возможности применения распределенных многопроцессорных вычислений с целью сокращения времени анализа.

Article considers the main aspects of application of modern methods of cryptanalysis for an assessment of strength of symmetric block algorithms of enciphering. Considering include such methods of the analysis as linear, differential, algebraic analyses and slide attack. The different variants of analysis of AES are considered. It is described what the Birthday Paradox is and what is its role in the information security. The special attention is given to questions of possibility of using of the distributed multiprocessing calculations for reduction of time of the analysis.
