Originální abstrakt

In this paper, we describe and analyze a blocked OCFB (so-called BOCFB) mode. This mode is a modification of the self-synchronizing OCFB mode, which consists in the following three adaptations. First, at the beginning of a new keystream generation, the detector of the synchronizing sequence is blocked for the period of transmitting r symbols. Second, if the last r symbols remain in the keystream block, then the generation of a new keystream block is initiated. Third, the synchronization sequence is only one bit long. In the BOCFB mode, there is r-times more time available for the keystream block generation than in the OCFB mode while simultaneously the self-synchronizing ability is preserved. For this reason, the BOCFB mode can be useful in fast data links.
