ZUC STREAM CIPHER USING FEEDBACK CARRY SHIFT REGISTER
Adusumilli Vijaya Bhaskar, C. R. S. Hanuman · 2012
This paper addresses the usage of FCSR in place of LFSR in a stream cipher. To demonstrate the usage ZUC stream cipher is taken as example in this paper. A good stream cipher should have good randomness, high period, linear span, and security against any known attack. FCSR’s provide greater non-linearity than LFSR’s.
