Jennings, "Linear equivalence of certain BRM shift-register sequences," in Electronics Letters, vol. Below I link to a couple resources for further reading on binary-rate multipliers (BRMs) and shrinking generators, if they are of interest. Note that this is only to give you an idea, and only holds for the cases described above. , $R_n$ are the shift registers and F is some boolean function. The scheme would look something like this, where $R_1$. This week I would like you to design and build a simple 8-bit random number generator using a linear feedback shift register. Ce que je veux envoyer en morse va se traduire par la séquence binaire suivante '249bits quelconques suivi de001010. Je dois générer et coder un message en morse mais surtout le redécoder par la suite. That is, the output of the feedback shift registers (linear or nonlinear) are combined in some way. Bonsoir a tous, Jai un petit problème de codage et décodage avec un linear shift register (LFSR). "Determined by multiple feedback shift registers" is somewhat vague, so I will give some concrete examples.įirst off, let's talk about nonlinear combiners. Question: How do you calculate the period of a stream cipher whose output is determined by multiple feedback shift registers (linear or nonlinear)? While I do believe I understand what you are asking for, I will rephrase my own interpretation of the question, and apologize if I have misunderstood the question.
