Abstract :
Linear feedback shift register (LFSR) is an important part of sequence cipher. In this paper, we introduce a kind of reconfigurable LFSR design. According to need, it can be configured to be a random LFSR to run over GF (2), GF (28) ,GF (216)or GF (232) in a certain length range. The prototype of the reconfigurable LFSR has been implemented in Altera´s EP2S60F1020C5 FPGA and its highest run clock is 100 MHZ. It is proved by experiment that the reconfigurable LFSR design uses few hardware resources and its performance is stable.
