System research and information technologies| Zusammenfassung: | New Boolean’s function concepts, such as correlation with a known function value and Boolean’s function extension, are introduced. Algebraic attacks on stream ciphers with linear feedback are shown to be reduced to approximation of the nonlinear filter using low-degree polynomials in terms of the correlation with the known function value. This kind of correlation can also be used in describing algebraic attacks on other types of ciphers. |
