substitution cipher

基本解釋

By itself, a rotor performs only a very simple type of encryption — a simple substitution cipher.
一個(gè)轉(zhuǎn)子單獨(dú)地執(zhí)行一項(xiàng)非常簡(jiǎn)單的加密法--- 一個(gè)簡(jiǎn)易的替代式密碼法。例如；
This paper proposes a matrix based substitution permutation network as the model of block cipher.
論文提出了一種基于矩陣的代替置換網(wǎng)絡(luò)模型。
Therefore, using large completely nonsingular matrix based substitution permutation networks can effectively improve cipher security in relation to differential cryptanalysis.
指出了使用大規(guī)模的基于全奇異矩陣的代替置換網(wǎng)絡(luò)可有效地提高分組密碼抗差分密碼分析的安全性。
