Analysis of cryptanalysis methods applied to stream encryption algorithms

Scientific-research work was carried out within the framework of ongoing research in order to create a durable stream encryption algorithm. In this research, cryptanalysis methods applied to stream encryption algorithms are studied. As a result of the reviewed analysis, it was determined that correlation attack type is the most widely used cryptanalysis method compared to stream encryption algorithms. It was determined that the correlation-immunity property of the combining function used in the combining generators provides tolerance compared to the correlation cryptanalysis method, and the use of a non-linear filtering function with the correlation-immunity property in the filtering generators increases the tolerance compared to the correlation cryptanalysis method.
