Abstract: The previous results about nonlinearity bounds of Boolean functions are compared and analyzed completely. For that, some problems which need research are pointed out. Especially, the nonlinearity bounds of functions with balancedness, with correlation-immunity, or with balanced correlation-immunity are discussed respectively. Using the relationship between nonlinearity and the order of correlation-immune, one upper bound of nonlinearity of correlation-immune functions is obtained.

Key words: cryptography, Boolean functions, nonlinearity, balancedness, correlation-immunity
