Abstract By using an m-sequence controlling a traditional feedforward stream cipher, this paper constructs a new feedforward network whose sequences have ideal balance, large period and linear complexity, it can also resist on linear approaching attack and correlation attack, at the same time it inherits the virtues of Bent functions’s even Walsh spectra.
