| Abstract: | In this paper,the common attributes and construction of the pseudo random sequences are researched.The m-sequence's feedback logic function in the stream cipher is presented.An improved pseudo-random bit generator(PRBG) is proposed to avoid m-sequence's weakness which has lower liner complexity and is easily being attacked.Theoretical and experimental results indicate that this new PRNG has good linear complexity and cipher performance. |
