cipher component 中文意思是什麼
cipher component
解釋
密碼元件-
In traditional block cipher, the s - box is the only one nonlinear core component and it determines the strength of these cryptosystems. therefore, the construction of cryptographically strong s - boxes is of much
在傳統分組密碼學中， s盒是唯一一個非線性運算部件，它的性能直接影響到整個密碼系統的強度，它的設計一直是密碼設計與密碼分析的研究重點。 -
In this paper, the general structure of block cipher together with its related properties is firstly discussed, then the main non - linear component of s - boxes in block cipher is analyzed. as to the boolean function in binary field, we studied its non - linearity, linearity structure, output bit independence criterion ( big ), balance, completeness, strict avalanche criterion, propagation criterion, correlation immunity, linear approximation table and xor distribution table. we also discussed the pile - up lama used to compute the combination linear probability and showed an instance of its application
本文首先討論了分組密碼的一般結構及其相關特性，此外還有分組密碼主要的非線性組成部分s盒。對於二元域上的布爾函數主要討論了其非線性性、線性結構、比特獨立準則、平衡性、完整性、雪崩準則、傳播準則、相關免疫性、線性分佈表及異或分佈表等特性。對計算組合線性概率的迭加定理我們也進行了具體的討論，並給出了運用事例。
