I want advice on Embedded Security Techniques

Embedded Security
1

Hello everyone,

I am working on a project that involves embedded security & i m looking for insights on effective techniques to secure microcontroller applications against various attacks; side channel attacks and fault injection.

I am familiar with some basic security principles but would like to dive deeper into specific strategies & best practices. Are there any recommended frameworks or libraries that you have found helpful?? I would appreciate any resources or case studies that highlight successful implementations of embedded security measures.

If anyone has experience with hardware based security features or has faced challenges in securing embedded systems, I’d love to hear your stories and recommendations. Your expertise would be invaluable as I aim to enhance the security posture of my project in the realm of cybersecurity.

As well, I found these resources when doing research on this; Advice on power side channel analysis & if anyone have any resources, tutorials or personal experiences please share with me, It would be greatly appreciated!!

Thank you… :grinning:

I don’t work much with countermeasures, so I’m far from an expert here, but I believe masking is your best bet for guarding symmetric crypto against power analysis, so I’d recommend looking into that.

For fault injection, the simplest answer I can give is building additional redundancy and fault tolerance into your code. Being able to handle variable corruption and instruction skips, for example, should go a long way in making it more difficult to glitch.
