　　Nonlinear feedback shift registers（NFSRs） are widely used as building blocks in the design of stream ciphers. Let NFSR（f） be an NFSR with the characteristic function f and let G（f） be the set of output sequences of NFSR（f）. For a given NFSR（f）, if there exists an affine Boolean function l such that G（l） ? G（f）, then G（l） is called an affine sub-family of NFSR（f）. In this paper, by skillfully combining previous ideas, the authors give a new upper bound on the order of affine sub-families of NFSR（...
