IoT Security Artifacts

Keys, Signatures, and Certificates

This was going to be an article about authentication. In putting it together, I realized that there are a number of fundamental concepts that can help the authentication discussion. Some of us tend to toss out words related to those concepts rather freely – and tentatively, perhaps, because if we were pushed hard, we’d have to admit that we don’t understand the details. And this is especially true in security, where those details tend to accrue only to a select few.

So if you’re a security whiz, what follows will all be familiar stuff. If you’ve dealt with browser security, it may also be familiar – because much of Internet of Things (IoT) security is based on existing technology, like TLS. But the IoT is bringing a lot of new folks into the game, and for them (or should I say, “us”), this stuff isn’t obvious.  Read More

I never found out! Guess it was something like shout louder.

(Almost) Like FPGAs, Only Better

Oh YES smiling

Now for a device that is the best of both ... large dense hard logic IP section for core invariant algorithms, plus a fair sized FPGA section, for the data center compute applications.

Thanks Kevin!
