attack-oriented 中文意思是什麼
-
The communist party must firmly develop socialist market - oriented economy with a clear - cut stand, at the same time, we should overtone the attack which is given by the principle of market - oriented economy
黨既要旗幟鮮明地發展社會主義市場經濟，同時又要克服市場經濟原則對黨的先進性的沖擊。 -
Then according to system simulation technology, the overall air - to - ground attack simulation plan is made with the thought of models and layers. after that, the mathematical models of main parts in the simulation are made such as aircraft body, propulsive system, flight control system, fire control system, bomb and air - to - ground missile. on the basis of these mathematical models, using the object - oriented design methodology, a set of air - to - ground attack real - time visual simulation software is developed. this software can be used to aid aircraft design, research of air - to - ground attack tactics and flight training
本文首先介紹了現代戰爭中空對地攻擊的技術裝備及其特點，計算機模擬技術的發展以及面向對象的軟體設計思想；而後使用系統模擬技術，依據分層、模塊化設計思想，制定了空對地攻擊模擬系統總體設計方案；之後根據目前技術狀況，建立了戰斗機機體、推進系統、飛控系統、火控系統、航空炸彈、空地導彈等子系統數學模型；在此基礎上，利用面向對象的軟體設計思想，在基於pc的平臺上開發了一套對地攻擊視景模擬軟體，實現了戰斗機對地攻擊實時視景模擬。 -
Obviously rc6 is not square - like cipher. square attack can only attack few rounds of rc6, because the data - rotations of rc6 affact the rules of propagation for active and passive words, which makes square attack ineffective. we analyse the square attack against serpent which is bit - oriented cipher, and the result shows that square attack on serpent is weak, because the bit - oriented linear operations interrupt the rules of propagation for active and passive multiset
我們將square攻擊應用於rc6密碼，發現square攻擊只能攻擊少數幾輪rc6 ，這主要是因為rc6的數據依賴循環運算打亂了活動位元組和固定位元組的傳播路徑，使得攻擊無法進行。我們分析了對serpent密碼的square攻擊， serpent密碼的按比特線性混合運算打亂了所構造multiset的傳播路徑，使得攻擊只能進行到3輪serpent密碼。 -
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。
