A curated list of research papers and blog posts on embedded security, keyed by the device p/n

The list below is compiled to inform, guide, and inspire budding security researchers. Oh and to pick something for bedtime reading too.

Included in the list are works on the following topics related to MCU/SoC security:

  • Secure boot
  • Fault injection
  • Side channel attacks

At the end of the list, there is also a section with links to articles of potential general interest, not addressing vulnerabilities in any specific device.

Grokking the coding interview equivalent leetcode problems

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window
