Abstract To validate the health management functions of Integrated Modular Avionics (IMA) systems, a technical solution for fault injection through Avionics Full-Duplex Switched Ethernet (AFDX) is presented. Under this solution, a configuration management method for fault data is proposed, along with a sending strategy to … Read more
Author | ktw624 Editor | Not Eating Pig Head Meat IntroductionWith the rapid development of intelligent connected vehicle technology, the driving experience and travel efficiency have significantly improved, and people’s attention to safety has also increased. To ensure driving safety, functional safety standards such as ISO 26262 impose strict requirements on automotive electronic and electrical … Read more
The focus of building virtual platforms often lies in system operation, especially in the field of digital twins for automotive and aerospace applications. Only by ensuring that the virtual platform can operate the system correctly can the software run reliably on the virtual platform. To ensure the system operates correctly, it is often necessary to … Read more
How can one know? This article is translated from the “2017 IEEE International Conference on Vehicular Electronics and Safety (ICVES)” Included article: Safety Assessment of Automated Vehicle Functions by Simulation-based Fault Injection Original authors: Garazi Juez, Estibaliz Amparan Editor’s note When analyzing the concept phase of automotive functional safety based on the existing version of … Read more
When conducting physical security assessments on IoT devices, one of the goals is to utilize debugging interfaces or accessible chips to study the device’s operation. Ideally, a complete file system is extracted from the device to find methods for gaining root access. This makes it easier to check which services are running, debug them if … Read more
Against the backdrop of the rapid and stable development of the digital economy, cloud computing has become the cornerstone of enterprises’ digital transformation. The application layer pursues more comprehensive, convenient, and faster services, which in turn drives the technology layer systems to become increasingly large, making it more challenging to maintain these systems. The occurrence … Read more
Abstract in Chinese: During the testing process of fault injection at the system level of an aircraft using the 1553B bus, common engineering issues are often encountered, such as difficulties in ensuring the real-time transmission of signals during the 1553B injection process, challenges in obtaining or frequently changing bus interface protocols, and onboard software that … Read more
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
Kerckhoffs principle states that the security of a cryptographic system relies solely on the security of the key, with everything else in the system considered public information. However, in reality, software reverse engineering and dynamic/static debugging techniques have successfully executed key extraction attacks on cryptographic systems. Given this fact, both the industry and academia have … Read more
Recently, while looking at the TiDB source code, I found that it used failpoint for fault injection, which I found very interesting. It involves code generation and parsing the code AST tree for replacement to implement fault injection. I will also try to analyze it and learn how to parse the AST tree to generate … Read more
