Abstract:
In this graduation work there were developed, software-implemented and tested out parallel algorithms
of searching slide pairs of texts for Magma cipher in the case of periodically repeated round subkeys.
Cases of self-similarity in one, two or four encryption cycles are examined. As a part of the study extensive
experimental data based on the method of slide attack were obtained. These data show the interaction
between computing speed in slide pairs of texts, cipher key and the number of computation nodes and
cipher characteristics.
