Ok. So the IoT garden must rewind to the Kerberos or physical provisioning. I can't imagine lattices on small silicon yet.
Thank you, Filippo.

@ohir @filippo I’m involved in modernizing crypto for protocol that needs to work at 9600 baud. These key sizes are going to be a terrible problem… and that’s just the bandwidth side, them there”s RAM and CPU on small embedded devices.

@ohir @filippo FN-DSA may be a solution for this class of devices. (Or LMS and XMSS, although those two are such a big footgun nobody should be using them, *especially* not for signing — verification is OK.)
