Simulation and analysis of the block cipher mode with statistical self-synchronization
 Kopčan, Marek ; Zezula, Radek (oponent) ; Burda, Karel (vedoucí práce)
There is a enormous rise in importance of cryptography. In age of hi-technologies, where information are the most valuable asset, is need to protect this value. But we need to transport information between us and keep information confidental. In this case we use special modes of block cipher because of defect in communication canal. Not all modes are able to deal with this problem. For this purpose, there are special modes. This work deal with self-synchronization modes of block cipher. It is protection of tranfered information in communication canal against different types of defects. We will exam two self-synchronization modes - OCFB (Optimized Cipher FeedBack) and SCFB (Statistical Cipher FeedBack). Both have their advantages and disadvantages. The goal of this work is to provide analyse of both modes and to create simulation model. This model should help with further research of self-synchronization modes.
