I attended the Community Connections Night for the Electrical and Computer Engineering department last night. The students set up maybe 10 different stands to pitch their projects and highlight some of their student organizations. I’ve been volunteering with this group for almost 10 years now. In these 10 years, I’ve only seen maybe 1 or… Read More

The board is slowing making its way to US distributors right now, which is good because Beagleboard… Read More

NIST announced in February the winner of the lightweight cipher competition. In this video I motivate WHY we even need lightweight ciphers in the first place using my favorite watch!
How to securely handle time on embedded systems? Do you trust your time or not? What should you do if the certificate expires? Where do you sync your time from? Read More
In this episode, I introduce the DICE (Device Identifier Composition Engine). I mentioned the motivation for the Trusted Computing Group (TCG) to make this standard and why its specifically tailored for embedded devices like MCUs and smaller controllers. Read More
In this episode I talk about the ATECC608 that’s on the SAMA7G Eval Kit and why, even though the SAMA7 includes TrustZone, you would want an external IC. Read More
Embedded Linux devices are generally lacking in security, but especially file system security. While I’m seeing the ship start to turn with respect to secure boot, there is still a wide lack of file system prevention and monitoring security. Read More
