An improved error - correcting decoding algorithm for a class of mds array codes 陣列碼的改進糾錯譯碼算法
This paper researches on the fast algorithm of hamilton array codes for high dimension and big hamming distance and key schedule algorithm based on hamilton array codes 本文主要針對快速高維大碼距hamilton陣列編碼的構造算法及其在分組密碼的密鑰編排算法中的應用進行了研究。
Lastly , we design a key schedule algorithm helped by lfsr and hamilton array codes . the innovation of the thesis is given bellow : first : construct and program the fast algorithm of hamilton array codes for high dimension and big hamming distance 本文的創新之處有: 1 、構造和實現了快速高維大碼距hamilton的陣列編碼構造算法; 2 、提出了一個基于lfsr和hamilton陣列編碼的通用密鑰編排算法。
The first kind of algorithm is based on s - box controlled by key , the algorithm distinguishes most of other block ciphers , its visible quality is that its s - box is not regular and fixative , but controlled by block cipher ' s key . the second kind of algorithm is based on smn ( d ) array code , it makes full use of the visible quality of smn ( d ) array code possessing big code distance ( d ) . the thesis discusses the two algorithms " reversibility , security and their qualities , the 第一種是基于“ s -盒由密鑰控制”的變結構分組密碼,該算法區別于其它大部分分組密碼最大的特點是它的s -盒不是固定不變的而是由密鑰控制產生;第二種是基于smn ( d )陣列編碼的變結構分組密碼,該算法充分利用了smn ( d )陣列編碼具有碼距大的特點;文中對這兩個算法的可逆性、安全性及其性能等進行了探討和分析,分析結果認為這兩個變結構算法正確、有效且安全。
Main contributions of this thesis are as follows : firstly , describe the theory of the hamilton array codes and its general construction . secondly , we construct and program the fast algorithm of hamilton array codes for high dimension and big hamming distance . thirdly , we discussion the design principle of the symmetry ciphers 內容包括:首先論述了hamilton陣列編碼的理論和常規構造方法;然后,構造和實現了快速高維大碼距hamilton的陣列編碼構造算法;接著,探討了對稱密碼(包括分組密碼和序列密碼)的設計原理,最后,結合lfsr和hamilton陣列產生通用密鑰編排算法。
In the paper , we construct the pseudorandom generator based on the hamilton array code and stream cipher after researching the theory of the hamilton array code and the technology of the encrypt . it can improve the ciphers " ability of resisting to many attacks if we use it to replace the key schedule algorithm of the ciphers 本文在研究了hamilton陣列編碼的理論與加密技術后,構造了一個基于hamilton陣列編碼和序列密碼的偽隨機產生器,這個產生器用來替代分組密碼算法的專用密鑰編排算法,可以提高算法的抗攻擊能力,從而實現了對稱密碼兩大領域的結合。
