Examples

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性、線性復(fù)雜度和初始密鑰的強度三個方面對算法進行了安全性分析，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中的偽隨機數(shù)發(fā)生器、 logistic混沌系統(tǒng)和rc4三種方法產(chǎn)生的二進制序列，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性和初始密鑰的強度，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性，得出初值和參數(shù)的最佳取值范圍。
