Generally due to silicon costs, the answers is no. Many choices of cryptographers are perfect on paper but impractical from the economic standpoint in the context of hardware. It's sad but it's ultimately about how cheap I can make my silicon. | |

| Jul 31, 2018 at 0:53 | comment | added | b degnan | @FutureSecurity I added the curve that I use, Curve25519, which is because it has a nice hardware implementation and I primarily do hardware. I worked with the Simon and Speck team as the unclassified member, so you are welcome to be annoyed as much as you want. (<128b) Simon and Speck were basically rejected for the Z constant explanation; however, I don't find much merit in that as they were simply based on the key expansion strength and a simple LFSR. There's over 90 papers trying to pick apart Simon and Speck, but nothing so far. It's super simple, so I doubt anything will be found. | |

added which specific curve I used

| Jul 30, 2018 at 21:15 | comment | added | Roland Smith | The problem with ECC is which curve to use. Not all are good. Also, SIMON and SPECK were rejected for ISO standardization because of the way the NSA handled them. Not something to fill one with confidence... | |
| Jul 30, 2018 at 21:14 | comment | added | Future Security | I can give this answer a +1 if you add more specifics. (Modes, key sizes, block sizes, and authentication algorithm. I'll also be a bit annoyed if you say something smaller than Speck128.) | |
