TY - JOUR TI - The Autocorrelation Theoretic Estimation of non-Linear Key Generator Sequences PY - %2023/%01/%25 Y2 - %2025/%12/%22 JF - مجلة المنصور JA - مجلة المنصور VL - 14 IS - 1 LA - en UR - https://journal.muc.edu.iq/journal/article/view/363 SP - 1-24 AB - The Randomness is one of the basic criterions to measure Key Generator Efficiency. The key generator depends basically on Linear FeedBack Shift Register which is considered as one of the basic units of Stream Cipher Systems. In this paper, the autocorrelation postulate, which one of the basis of Randomness criteria, is calculated theoretically for non-linear key generator before it be implemented or constructed (software or hardware), this procedure save time and costs. Two non-linear key generators are chosen to apply the theoretical studies, these key generators are the Product and Brüer. ER -
