Implementation of Pseudo-Random Number Generator Using LFSR

, 2020
Linear Feedback Shift Registers (LFSR) play a vital role to provide cybersecurity for the data communication system. LFSR is a shift register where the input is linear of its previous states. The most important application of LFSR is the device’s ability

Maximum Likelihood Binary Shift-Register Synthesis from Noisy Observations

, 2001
We consider the problem of estimating the feedback coefficients of a linear feedback shift register (LFSR) based on noisy observations. In the current approach, the coefficients are endowed with a probabilistic model.
