Differences and Similarities Between IoT and Edge Computing

Introduction: As more and more IoT devices connect, they generate massive amounts of data. However, sending all this data to the cloud for processing may be counterproductive. Edge computing pushes data processing closer to the source (sensor devices) instead of sending it to a centralized cloud located thousands of miles away. In recent years, low-cost … Read more

Dynamic Fault Injection Practice on White-box Cryptography Using Unicorn

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
