电磁故障注入(EMFI)被认为是对集成电路进行物理攻击的一种有效的故障注入技术。它使对手能够在电路上注入错误，以获取敏感信息或绕过安全功能。本文的目的是重点介绍一种廉价、可编程的电磁脉冲注入平台--SilicToaster的设计和验证。它的设计使用了低成本和容易找到的组件。此外，它可以注入高达1.2千伏的可编程电压的故障，而不需要外部电源，因为它是由USB供电的。论文的第二部分对SilicToaster进行了投资，以绕过STM32F2微控制器的固件安全保护。首次以非侵入性方式(无需芯片解封)顺序绕过了两个安全级别。
Electromagnetic Fault Injection (EMFI) is considered as an effective fault injection technique for the purpose of conducting physical attacks against integrated circuits. It enables an adversary to inject errors on a circuit to gain knowledge of sensitive information or to bypass security features. The aim of this paper is to highlight the design and validation of SiliconToaster, which is a cheap and programmable platform for EM pulse injection. It has been designed using low-cost and accessible components that can be easily found. In addition, it can inject faults with a programmable voltage up to 1.2kV without the need to an external power supply as it is powered by the USB. The second part of the paper invests the SiliconToaster in order to bypass the firmware security protections of STM32F2 microcontroller. Two security levels were bypassed sequentially for the first time in a non-invasive way (without chip decapsulation).
