@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.

@mikaeleiman @ohir yup, it's not great, but it is what it is. (RAM is kinda fine if you optimize for it, and CPU is actually faster than classical. But yes, size sucks.)

@mikaeleiman > there”s RAM and CPU on small embedded devices. This. You can think of attesting just KDC with ML signature, likely, on some bigger silicon, but not on a half of coming cheap STM lines for example. Time to study rfc4120 and siblings :( @filippo I'd like to ask whether migrating Ed25519 to Ed448 makes any sense? At least temporarily. Setting aside all that owful implementation disadvantages of Ed448.
