Side Channel Analysis (SCA) presents a clear threat to privacy and security
in modern computing systems. The vast majority of communications are secured
through cryptographic algorithms. These algorithms are often provably-secure
from a cryptographical perspective, but their implementation on real hardware
introduces vulnerabilities. Adversaries can exploit these vulnerabilities to
conduct SCA and recover confidential information, such as secret keys or
internal states. The threat of SCA has greatly increased as machine learning,
and in particular deep learning, enhanced attacks become more common. In this
work, we will examine the latest state-of-the-art deep learning techniques for
side channel analysis, the theory behind them, and how they are conducted. Our
focus will be on profiling attacks using deep learning techniques, but we will
also examine some new and emerging methodologies enhanced by deep learning
techniques, such as non-profiled attacks, artificial trace generation, and
others. Finally, different deep learning enhanced SCA schemes attempted against
the ANSSI SCA Database (ASCAD) and their relative performance will be evaluated
and compared. This will lead to new research directions to secure cryptographic
implementations against the latest SCA attacks.

现代计算系统中，侧信道分析（SCA）对隐私和安全构成明显威胁。大部分通信通过加密算法来保护，尽管这些算法从密码学角度通常是安全的，但实际硬件上的实现会引入漏洞。本研究关注最新的深度学习技术在侧信道分析中的运用，探讨了深度学习技术的理论基础和实际操作。主要研究重点放在利用深度学习技术进行分析的攻击模式，以及一些新兴的由深度学习技术加强的方法，如非基于剖析的攻击、人工迹线生成等。最后，我们将评估和比较针对 ANSSI SCA 数据库（ASCAD）的不同深度学习增强的侧信道分析方案及其相对性能。这将为安全密码学实施抵御最新侧信道分析攻击的研究方向提供新的参考。
