LFSR-based Stream Ciphers In order to minimize the size of the internal state, stream ciphers dedicated to low-cost hard- ware implementations may use a linear transition function. Among all such possibilities, linear feedback shift registers (LFSRs) offer several advantages including their performance, their implementation cost and many theoretical results on the statistical properties of the
