Abstract

Side-channel attacks are among the most powerful and cost-effective attacks on cryptographic systems. Simulators that are developed for side-channel analysis are very useful for preliminary analysis of new schemes, in depth analysis of existing schemes as well as for analysis of products on early stages of development. The contribution of this paper is three-fold. We present a first survey of existing simulators that were build for side-channel analysis. We present a new open-source simulator SAVRASCA that can generate simulated power traces based on compiled binary files for many popular AVR microcontrollers. We show how to use our simulator on the example of DPA Contest 4 and we find a new vulnerability that allows an attacker to mount a differential power analysis (or even simple electro-magnetic analysis) attack on the scheme. Our simulator can be used during development of new products in order to test their resistance against side-channel analysis. We also focus the attention of readers on questions of why and how simulators are useful in this domain and try to highlight main issues related to simulators that were developed by the community.

使用模拟器进行侧信道分析

侧信道攻击是对密码系统最强大、最经济有效的攻击之一。为侧信道分析而开发的模拟器对于新方案的初步分析、对现有方案的深入分析以及对处于开发早期阶段的产品的分析都非常有用。本文的贡献有三方面。我们提出了现有的模拟器的第一个调查，建立了侧信道分析。我们提出了一个新的开源模拟器SAVRASCA，它可以基于编译的二进制文件为许多流行的AVR微控制器生成模拟电源跟踪。我们在DPA Contest 4的示例中展示了如何使用我们的模拟器，并发现了一个新的漏洞，该漏洞允许攻击者对该方案进行差分功率分析(甚至是简单的电磁分析)攻击。我们的模拟器可用于新产品的开发，以测试其对侧信道分析的抵抗力。我们还将读者的注意力集中在模拟器为什么以及如何在这个领域有用的问题上，并试图突出与社区开发的模拟器相关的主要问题。
