Summary

This blog previews a hands-on workshop showing how AES implementations can leak secret keys through power side-channels and how an ordinary oscilloscope plus basic math can recover them. Readers will see practical demonstrations of trace acquisition, simple signal processing, and attack workflows used to break AES on real embedded devices.

Key Takeaways

• Capture power traces from a microcontroller using an oscilloscope and minimal probe setup
• Apply basic signal processing and correlation techniques to extract AES key bytes from measured traces
• Identify common implementation mistakes that enable power-based side-channel leakage
• Implement and evaluate practical countermeasures and testing methods to reduce leakage

Who Should Read This

Embedded firmware engineers, security researchers, and IoT device developers with an interest in hardware Safety/Security who want to learn practical side-channel testing and defenses.
