A Pseudo-random Number Generator Based on Linear Feedback Shift Register

In the fields of information hiding and digital watermarking, a pseudo-random integer sequence, that has enough long period, is needed so as to avoid repeatedly embedding secret information at the same position.In this paper, based on linear feedback shift register theory, a random integer generator is proposed, and this new generator can generate integer sequence with any given period, It provides an experimental platform for further research on applications of random number.
