At last , based on amsaa model , the sequential testing approach is presented by bayesian method , while testing analysis and evaluation in small - sample circumstances is taken into account . and the optimal sample size is evaluated in given testing circumstances 最后,在amsaa模型的基礎(chǔ)上,結(jié)合小子樣試驗(yàn)分析與評(píng)估技術(shù),利用貝葉斯方法建立了可靠性增長(zhǎng)的序貫試驗(yàn)方法,并對(duì)給定條件下試驗(yàn)的最優(yōu)樣本量進(jìn)行了評(píng)估。
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(gè)方面對(duì)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(guò)了頻數(shù)檢驗(yàn)、序列檢驗(yàn)、撲克檢驗(yàn)、自相關(guān)檢驗(yàn)和游程檢驗(yàn)等5種統(tǒng)計(jì)檢驗(yàn)方法的檢驗(yàn),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。
Besides , how to improve sequential test is discussed . then , the data structure design of reliability block diagram and assessment algorithms of system reliability software is discussed , the method how to resolve the key problems is given , the functions of the software and how to use is introduced , too 同時(shí),以二項(xiàng)分布為例,討論了序貫檢驗(yàn)方法的改進(jìn)然后,討論了武器系統(tǒng)可靠性評(píng)估軟件的可靠性框圖數(shù)據(jù)結(jié)構(gòu)設(shè)計(jì)和評(píng)估算法實(shí)現(xiàn),給出了關(guān)鍵問(wèn)題的解決辦法,簡(jiǎn)要介紹了軟件的功能與使用。
