There is also no real need. Reduced round Salsa/ChaCha (12 rounds) is tiny and likely fast enough for the quantities of data any microcontroller would need to push over a network. Those ciphers were designed in the open and have been heavily analyzed with no attacks known against more than a few rounds. Why not use those?
- makomk 8y agoIn general that's true, but if I understood the discussion correctly the reason Speck was being considered here is because this specific application needed a fast block cipher - stream ciphers like Salsa/ChaCha were not suitable.
