Analysis Of Boolean Function For Cryptographic

Boolean functions is a kernel role in stream ciphers. Researching Booleanfunctions is key piont in stream ciphers. Algebraic attacks is important in thecryptographic. Boolean functions must good properties that is highnonlinearity and algebraic immunity and degree, balancedness. The mainresults are as follows. Algebraic immunity of Boolean functions and newalgebraic immunity character and the reducibility of boolean functions.Boolean functions and new algebraic immunity character and the reducibilityof Boolean functions maybe affect algebraic attacks. In thesis we happenedproblems and we solve those use boolean functions. Firstly problem ispujiang Vocational school teaching management software how encryption.Wecan use LILI-128algorithm to solve it and it has good algebraic immunity andwe test it randomness. Secondly Problem is this Vocational school Testmanagement software load management. We use boolean functions solve it.Thirdly problem is this Vocational school test management software choicesexamination questions management. We use boolean functions solve it. My research appl y the act ual project is success.
