English Abstract	Dynamic linear feedback shift register (DLFSR) was a popular way to irregular clocking the linear feedback shift registers, which had a better tradeoff between the security and efficiency. Through analysis of the DLFSR in stream cipher RAKAPOSHI, a RAKAPOSHI-like DLFSE model was presented, and the sufficient and necessary condition was analyzedfor its output sequence being periodic. Furthermore, the relationship of the period between controlled sequence and output one was explicie, and finally the condition for the output sequence to be the maximal sequence was obtained. Based on these results, a naive search algorithm was given for finding maximal period RAKAPOSHI-like DLFSE.; Dynamic linear feedback shift register (DLFSR) was a popular way to irregular clocking the linear feedback shift registers, which had a better tradeoff between the security and efficiency.
