一類平衡前饋序列的構(gòu)造與性質(zhì)
Construction and Properties of Balance Feedforword Sequences
-
摘要: 該文采用m序列選控傳統(tǒng)前饋密碼系統(tǒng)的方法，在繼承了Bent函數(shù)譜值均勻優(yōu)點(diǎn)的同時(shí)，使得產(chǎn)生的序列具有理想的平衡性、大的周期和高的線性復(fù)雜度，且能抵抗現(xiàn)有的線性逼近攻擊和相關(guān)攻擊。

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 functionss even Walsh spectra. -
