  2. Concentrating on security analysis and design of block ciphers, five principal achievements have been obtained in this dissertation : 1. using differential - nonlinear cryptanalysis, truncated differential - linear cryptanalysis and integral cryptanalysis respectively, three attacks of reduced - round safer + + are given ; 2. based on the survey of provable security and practical security of block ciphers, a block cipher model of spn cipher containing feistel structure is proposed

    分別利用差分-非線性密碼分析、截斷差分-線性密碼分析、積分密碼分析三種不同的密碼分析方法，對safer + +進行了密碼分析； 2在對分組密碼的可證明安全性和實際安全性研究的基礎上，提出了一個嵌套feistd結構的sp型分組密碼的模型。
  3. The traditional encryption algorithm ' s security intensity is scarcity, its key " length is too short to resist the attack of the differential cryptanalysis and linear analysis, and exist considerable serious safe trouble

    傳統的des等加密演算法安全強度不足，主要表現在密鑰長度過短、不能抵禦差分分析和線性分析攻擊，因而存在相當大的安全隱患。
  4. Aes - ccm mode use counter mode application simple, systematic expense little, may raise the efficiency of encryption. aes algorithm is presented in allusion to differential cryptanalysis and linear analysis. therefore, the security of aes algorithm in current stage have enough guarantee

    而aes演算法是針對差分分析和線性分析提出的，它的最大優點是可以給出演算法的最佳差分特徵的概率及最佳線性逼近的偏差界，具有抵抗差分密碼分析及線性密碼分析的能力，因此aes演算法的安全性在現階段是有足夠保障的。
  5. According to features of the s and p layers, ability which rijndael algorithm has to resist against differential cryptanalysis and linear cryptanalysis is theoretically discussed, and the principle of square basic attack and two kinds of extension attacks are discribed on the basis of the characteristics of oriented - byte of rijndael algorithm

    根據s層和p層的性能，從理論上定量討論了rijndael演算法抵抗差分密碼攻擊和線性密碼攻擊的能力。同時，基於rijndael演算法面向位元組結構的特點，闡述了square基本攻擊及其兩種擴展攻擊的原理。
  6. The additional operation to pad 0 or 1 to the beginning of the message blocks makes the length extension attack not to be work. the method to construct the encryption block based on aes makes the algorithm stay safe under the differential cryptanalysis. the secure domain extension method makes it resist on the multi - collision attack

    演算法附加的填充操作使它能抵抗長度擴展攻擊、所採用的基於aes的加密模塊使它能抵抗差分分析、採用的安全的域擴展使它能抵抗多沖突攻擊、採用的安全pgv方案使它能有效抵抗固定點攻擊;總體上，它能達到
  7. As far as kasumi algorithm is concerned, we get the maximum probability of differential and linear through computing the s7 box and s9 box ' s differential and linear probability. thus, we prove it is secure against differential and linear cryptanalysis

    在kasumi演算法的分析中，首先計算出s7盒與s9盒的最大差分概率和最大的線性概率，最後計算出整個演算法的最大差分概率和最大線性概率，進而證明了該演算法是抗差分分析和線性分析的。
