Generalized Self-Shrinking Generator
Yupu Hu, G. Xiao · IEEE Transactions on Information Theory · 2004
In this correspondence, we present a simple bit-stream generator. It is a specialization of shrinking generator and a generalization of self-shrinking generator. We call it "generalized self-shrinking generator." The family of such generated sequences has a group structure. The correlation between the sequences is quite good and the sequences themselves are balanced. For each k, 0<k<n, no more than 1/2/sup n-k/ of the sequences have least periods less than 2/sup k/. No more than 1/4 of the sequences have least periods less than 2/sup n-1/. There are two sequences with least periods of 2. There is no sequence with a least period p such that 2<p
