【摘要】：隨著信息技術(shù)、計(jì)算機(jī)技術(shù)及微電子技術(shù)的高速發(fā)展，物聯(lián)網(wǎng)作為新一代的信息技術(shù)，正深入到我們生活的各個(gè)領(lǐng)域，各種銀行卡、公交卡充斥著我們的日常生活。這些便攜式的密碼設(shè)備，其電路規(guī)模和能量提供的限制決定了其計(jì)算能力和存儲(chǔ)空間都是極其有限的。KLEIN是2011年提出的輕量級(jí)分組密碼算法，與其他的密碼算法相比，它的執(zhí)行效率更高、資源消耗更低，是密碼算法中的佼佼者。不僅如此，KLEIN采用了面向軟件的設(shè)計(jì)思想，使得它應(yīng)用范圍更廣，并且更加便于維護(hù)。 信息技術(shù)的飛速發(fā)展確實(shí)給我們的生活帶來(lái)了極大的便利，，但與此同時(shí)也帶來(lái)了日益嚴(yán)峻的安全問(wèn)題。傳統(tǒng)密碼學(xué)研究主要關(guān)注的是密碼設(shè)備使用的密碼算法在數(shù)學(xué)分析上是否安全，將密碼設(shè)備抽象為一個(gè)數(shù)學(xué)問(wèn)題進(jìn)行分析研究,但是密碼算法始終是要實(shí)現(xiàn)為一個(gè)密碼設(shè)備并在實(shí)際的物理環(huán)境中運(yùn)行的。設(shè)備在實(shí)際環(huán)境運(yùn)行的過(guò)程中不可避免的會(huì)泄露出一些物理信息，通過(guò)采集密碼設(shè)備在運(yùn)行過(guò)程中泄露的這些物理信息進(jìn)行分析，我們將有可能分析得出密鑰。這類攻擊方法稱之為側(cè)信道攻擊(SCA)。 能量分析攻擊是最簡(jiǎn)單也是最有效的側(cè)信道攻擊方法，它通過(guò)分析密碼設(shè)備運(yùn)行過(guò)程的能量消耗數(shù)據(jù)來(lái)得出密鑰，給密碼設(shè)備的實(shí)際安全性造成了極大威脅，受到了密碼學(xué)領(lǐng)域的廣泛關(guān)注，許多的攻擊方法和防御方法相繼被提出來(lái)。基本的能量分析攻擊方法包括簡(jiǎn)單能量分析攻擊和差分能量攻擊，之后又出現(xiàn)了差分能量分析攻擊的改進(jìn)方法如相關(guān)系數(shù)能量分析攻擊(CPA)、互信息能量分析攻擊(MIA)，以及針對(duì)防御方法的高階的能量分析攻擊方法如高階相關(guān)系數(shù)能量分析攻擊(HOCPA)等。 本文論述了對(duì)KLEIN進(jìn)行能量分析攻擊研究的意義，搭建了仿真平臺(tái)系統(tǒng)采集KLEIN加密過(guò)程中的能量消耗數(shù)據(jù)，分析了KELIN的算法流程并對(duì)KLEIN進(jìn)行了相關(guān)系數(shù)能量分析攻擊和互信息能量分析攻擊，最后實(shí)現(xiàn)了KLEIN的掩碼方案。
[Abstract]:Along with the high - speed development of information technology , computer technology and micro - electronics technology , Internet of Things , as a new generation of information technology , is going deep into every field of our life , various bank cards and public transport cards are full of our daily life . These portable cryptographic devices , whose circuit scale and energy supply limit determine their computing power and storage space are extremely limited .

The rapid development of information technology does bring great convenience to our life , but at the same time , it brings about the increasingly serious security problem . The traditional cryptography research mainly focuses on whether the cryptographic algorithm used by the cryptographic device is safe in the mathematical analysis , but the cryptographic algorithm is always to be implemented as a cryptographic device and run in the actual physical environment .

Energy analysis attack is the simplest and most effective method of side - channel attack . It can obtain the key by analyzing the energy consumption data of the cryptographic device ' s operation process . It is widely concerned in the field of cryptography , and many attack methods and defense methods have been put forward successively . The basic energy analysis attacking method includes simple energy analysis attack and differential energy attack , and then the improved methods of differential energy analysis attack such as correlation coefficient energy analysis attack ( CPA ) , mutual information energy analysis attack ( MIA ) , and high order energy analysis attack method for defense method , such as high order correlation coefficient energy analysis attack ( HOCPA ) , etc .

In this paper , the significance of energy analysis and attack on KLEIN is discussed . The energy consumption data in KLEIN encryption process is set up . The algorithm flow of KLEIN is analyzed , and the correlation coefficient energy analysis attack and mutual information energy analysis attack are carried out on KLEIN . Finally , the mask scheme of KLEIN is realized .
