A New Straightaway Output Controlled Generator On GF(3)

In this paper, we use two mm-sequences construct a new kind of one-way complex con-trolled generator on GF(3).Suppose both A={a*}, B={bj}, C={ck} are mm-sequence,to j=0,1,2,……,the models are as follows:if bj=o, the generator outputs the aj;if bj= 1, the generator outputs the aj+1;if bj= 2, the generator outputs the aj+2, This paper gives the peri-od and the linear complexities.Then improve the one-way complex controlled generator a new one-away output controlled generator on GF(3).The models are as follows:to k=0,1,2,…,if ak=1, the generator output ak+1;if ak= 2, the generator output ak+2;if ak=0, the generator output ck;This paper gives the pseudo-randomness of the new one-away output controlled gen-erator,for example,the period,the linear complexities, the balance properties and stability and so on. And mainly studied the run distributions. And then simplify the models construct a new one-away output key flow generator use one mm-sequence on GF(3).The models are as follows :to k=0,1,2,…,if ak=1, the generator output ak+1;if ak=2, the generator output ak+2;if ak=0, the generator give up output;And studied the run distributions.It is shown that it is run distributions is roughly the same as the m-sequences.From a series of conclusions shown the new straightaway output controlled generator on GF(3) has a huge period, a high linear complexity,a good balance property and good run distributions and has powerful ability of preventing attacks and easy to achieve,it is a good pseudo random key stream.
