zuc主要由lfsr線性反饋移位暫存器, br位元重組和f非線性函式三部分組成;
工作階段:
\(z_0||z_1||z_2||z_3\);
lfsr初始化模式
\(s_0, s_1, \dots, s_ = s_1, s_2,\dots, s_\)
lfsr工作模式
\(s_0, s_1, \dots, s_ = s_1, s_2,\dots, s_\)
l_1(x):
l_2(x):
s(x):
金鑰裝入是將128位長的金鑰\(k\)和128位長的初始向量\(iv\)擴充套件為16個31位長的字, 並放入lfsr的16個暫存器\(s_0,s_1,\dots,s_\)中的過程.
\(s_i = k_i || rightmost_(kd[i]) || iv_i\), \(kd\)是大小為16的元素為16位長度的常量表(見附錄), \(rightmost_l(x)\)表示取\(x\)的最右邊\(l\)位位元位;

流密碼（序列密碼）與Rc4演算法
流密碼 序列密碼 與rc4演算法 rc4是一種序列密碼，它是一種可變金鑰長度 面向位元組操作的序列密碼，乙個明文位元組與乙個金鑰位元組相異或產生乙個密文位元組。演算法原理 對於n 8位長的字，即以乙個位元組為單位，此時n 256，用從1到256個位元組的可變長度金鑰初始化乙個256個位元組的狀態向量...
古典密碼演算法 替代密碼演算法
替代密碼演算法 的原理是使用替代法進行加密，就是將明文中的字元用其它字元替代後形成密文。例如 明文本母a b c d 用d e f g做對應替換後形成密文。替代密碼包括多種型別，如單錶替代密碼 多明碼替代密碼 多字母替代密碼 多表替代密碼等。下面我們介紹一種典型的單錶替代密碼，愷撒 caesar 密...
