![]() Sensitive data is also part of our everyday life. Working with image makes me working with large field of data, Kb files. An Introduction to Cryptography and Linear Feedback Shift Registers Magdalena Stenius All around us data is transferred faster than ever. With N bits a Maximal LFSR will have (2N) - 1 states. ![]() When considering the implementation of the LFSR, the bit width of the random number and the repeatability of the number need to be considered. It says: "Despite this simplicity, there are currently no known attacks better than exhaustive search when the feedback polynomials are secret" Implementation is relatively simple, a shift register with a number of terms XORd together to create the feedback term. In the wikipedia article they recommend to use combination of several LFSR, we could use 2 LFSR, one could tell if we use the current output bit from the other one shrinking generator In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. I would like to use LFSR to generate a stream cypher in each Core of the GPU. I am currently working on a project which consist in the encryption of image using the GPU of a raspberry.
