摘　　要：随着密码技术和信息技术的发展,目前的密码算法本身已足够强大,能够对抗传统的密码分析手段,但由于设备本身的工艺特性,其运行时会泄露如功耗、电磁、时间等侧信道信息,这些信息可以被攻击者利用,破解密钥。因为这种攻击效果好,所以最开始比较受欢迎。模板攻击由Rohatgi等人首次提出,和差分功耗攻击不同的是,它需要攻击者预先刻画密码芯片的模板,然后进行模板匹配,攻击时攻击者可以提取感兴趣的部分,因为监督学习和这种攻击过程很类似,所以机器学习在侧信道领域应用越来越广。之后Martinask等人将深度学习方法引入模板攻击,结果表明攻击效果优于其他训练算法。该文首先介绍了侧信道攻击的发展情况、概述、分类,之后结合最近几年机器学习技术的发展,阐述了人工智能在侧信道攻击技术方面的应用。With the development of cryptography and information technology,the current cryptographic algorithm itself is strong enough to fight against the traditional cryptanalysis methods.However,due to the process characteristics of the device itself,it will leak side channel information such as power consumption,electromagnetic,time and so on,which can be used by attackers to crack the key.In many side channel information,the acquisition of power consumption information is relatively simple and low cost,but it has a strong attack effect.The template attack was first proposed by Rohatgi et al.Different from the differential power attack,it requires the attacker to characterize the template of the cryptographic chip in advance,and then match the template to the attacking device.During the attack,the attacker can extract the interested part,because the attack process of the template attack is similar to supervised learning,so many machine learning algorithms are introduced into the field of side channel attack.After that,Martinask and others introduced the deep learning method into the template attack,and the results show that the attack effect is better than other training algorithms.In this study,we first introduce the development,overview and classification of side channel attack,and then combined with the development of machine learning technology in recent years,expound the application of artificial intelligence in side channel attack technology.
