摘要：Pseudo-random number generators (PRNGs) are a key component of stream ciphers used for encryption purposes. While Non li near Feedback Shift Registers (NFSRs) combined with cellular automata has b een utilized for P RNGs, the use of cellular automata (CA) is another viable opti on. Thi s paper explores the combi nation of NFSRs and CA as the key components of an efficient stream cipher desi gn for implementat ion on Fi eld Programmable Gate Arrays (FPGAs). The proposed stream cipher design builds upon a recent published design known as A2U2, which uses the principles of stream cipher and approaches from block cipher design. Comparisons with the A2 U2 d esig n indicate that the use of CA have the potential to improve the quality of the random numbers generated and hence increase the security of the cipher
