Tl;dr - Choosing parameters for ECC is very important but also very difficult. Also, ECC is more resistant to quantum algorithms than RSA.

I didn’t know about the PQC readiness of ECC so thank you!

To my understanding, picking the right ECC parameters is critical to ensuring large enough entropy that it can’t be brute forced. There are a lot of weak and easy to compromise parameters, and a lot of trust has to be put in the standards organizations declaring which ones are “safe” like the NIST curves. Or you can choose your own, with a lot of risk associated.

There’s also the fact that I believe there’s more potential to leak info/expose side channels on the embedded devices running these protocols (I’ve personally had to worry at work!)

interesting about the security, it looks like ECC is arguably more secure against quantum algorithms? I first learned about all of this stuff about 10 years ago, and I only vaguely remember reading about the pqc resistance. Thanks for the update on that!

Edit: But I want to be clear I’m not a security expert, just some lady whose had to deal with embedded cryptography from time to time.

Ohhh so that’s what they meant by putting IoT nodes on the Edge!

And if I remember correctly, I believe it has more weaknesses (especially potential unknown ones) than RSA.

But it’s definitely more efficient on embedded hardware, and for sure still gets used in that space. Not that I’d know cough cough

This feels like a Ryan Gosling reskin of a 3Blue1Brown video 😅 (which I guess really isn’t even a little surprising… But it’s a chance spread the good word of Mr. Sanderson!)

But unfortunately you can’t start it again.
