initial key造句
例句與造句
- At the precision of 64 bits , even if a variable in the initial key has a minute difference about 10 - 15 , any information about the original plaintext ca n ' t be obtained
在64位的精度下，即使初始密鑰中的一個變量有10 - 15的微小差異，密碼分析者也根本無法得到原始明文的任何有關(guān)信息。 - Under the condition of the precision of p bits and regardless of the absolute value less than , the space of initial key is about , the entropy of system is about ( 5p + 20 ) / 6 , which comes up to the demand of the security at the sense of modern cryptology
同時，初始密鑰也具有很高的強(qiáng)度，采用p位精度且不考慮絕對值小于的值時，初始密鑰空間的大小k約為，系統(tǒng)的熵h ( k )約為( 5p + 20 ) / 6 ，完全符合現(xiàn)代密碼學(xué)意義下的安全性要求。 - The security of the algorithm is analyzed from the randomness , linear complexity of the chaotic sequence and the intensity of initial key . the results show the randomness of the key sequence pass the frequency test , sequential test , poker test , autocorrelation test , runs test , etc . and the total level is better than the binary sequence generated by the prng of delphi 7 . 0 , logistic chaotic system and rc4 , the linear complexity comes up to the expectation , the initial key has very strong intensity
本文最后從混沌序列的隨機(jī)性、線性復(fù)雜度和初始密鑰的強(qiáng)度三個方面對算法進(jìn)行了安全性分析，結(jié)果表明算法產(chǎn)生的密鑰序列的隨機(jī)性完全通過了頻數(shù)檢驗、序列檢驗、撲克檢驗、自相關(guān)檢驗和游程檢驗等5種統(tǒng)計檢驗方法的檢驗，而且整體水平要好于delphi7 . 0中的偽隨機(jī)數(shù)發(fā)生器、 logistic混沌系統(tǒng)和rc4三種方法產(chǎn)生的二進(jìn)制序列，線性復(fù)雜度達(dá)到了數(shù)學(xué)期望值。 - Since the security of stream cipher depends on the randomness of key sequence and the intensity of the initial key , first we analyze sensitiveness of lorenz chaotic system to initial conditions and parameters , and non - periodicity and pseudo - randomness of the chaotic sequence generated by lorenz chaotic system . the optimum domain of initial values and parameters is obtained
由于序列密碼算法的安全性依賴于密鑰序列的隨機(jī)性和初始密鑰的強(qiáng)度，我們首先從動力系統(tǒng)的運動性態(tài)著手，分析了lorenz混沌系統(tǒng)對初始條件和參數(shù)的敏感性以及由其生成的混沌序列的非周期性和類隨機(jī)性，得出初值和參數(shù)的最佳取值范圍。 - It's difficult to find initial key in a sentence. 用initial key造句挺難的
