  • Abstract
    A new type of cascaded clock-controlled system is proposed. There are r+1 linear feedback shift registers (LFSRs) of length n in the system if the degree of cascade connection is r. It is proved that for an rth degree cascade the output sequences have linear complexity n Sigma i=0r (2n-1)i, period (2n-1)r+1 and good statistical properties. Such a model can generate key stream sequences of stream ciphers in computer applications.
