Studying the Impact of Fault Injection on Processor States via Step Debugging

Studying the Impact of Fault Injection on Processor States via Step Debugging

0x01 Basic Overview Fault injection is a side-channel attack technique that introduces a certain form of disturbance or invalid state into a system to alter its behavior. Typically, in embedded hardware and electronic devices, this disturbance can take various forms. Common methods of fault injection in electronic devices include: – Clock glitch injection (imposing erroneous … Read more

Understanding Interrupt Systems in MCUs and RTOS

Understanding Interrupt Systems in MCUs and RTOS

Abstract:We encounter many operating systems, such as Windows, Android, iOS, and Linux, which are all types of operating systems. Microcontrollers also have their own operating systems, known as real-time operating systems. So what are the differences between these real-time operating systems and the systems we use? The operating systems we commonly use are actually non-real-time … Read more
