Measuring EMF and Internal Resistance of Dry Batteries Using ESP32 and Phyphox

Measuring EMF and Internal Resistance of Dry Batteries Using ESP32 and Phyphox

Recently, inspired by a high school physics exam experiment question, I decided to use the voltage-resistance method to measure the electromotive force (EMF) and internal resistance of a dry battery. A few days ago, I used the ESP32 and Phyphox to measure the EMF and internal resistance of a simulated power supply using the voltage-resistance … Read more

Drone Security and Fault Injection Attacks

Admin’s Note: It’s been a while since I posted a new article and logged into the public account. Unfortunately, many issues beyond my control, combined with my principle of not being a mere transporter, mean that creation always takes time. Today, I am back with an interesting topic for everyone. Drone Security and Fault Injection … Read more

Automotive Chip Security Testing Using Electromagnetic Fault Injection

Automotive Chip Security Testing Using Electromagnetic Fault Injection

For more information and discussions, please contact “Niu Xiaoka” on WeChat: NewCarRen Abstract Electromagnetic Fault Injection (EMFI) is a well-known method for introducing faults for the security analysis of digital devices. Such faults can be viewed as similar to those known to occur naturally in digital devices, which is a recognized issue in designing safety-critical … Read more
