  • Abstract
    We have derived a lower bound on the linear span of a binary sequence generated by a feedback with carry shift register (FCSR) under the following condition: q is a power of a prime such that q=re (e⩾2) and r(=2p+1), where both r and p are 2-prime. This allows us to design FCSR stream ciphers similar to previously proposed linear feedback shift register (LFSR) stream ciphers
