dear list, with the spectre of IoT looming over us - making us all warm and fuzzy about our memories of security in the 80ies - i was wondering, if you have an 32bit (not considering 8bit systems for their very limited support for crypto) embedded device with heavily constrained processing power and memory (<0.5MB) but still enough to perform all basic crypto algos, how would it be the best do derive a key from user input (assuming we have a keypad e.g.) argon2 seems to be optimized for PCs. is the best one can do in such situations a naive:
H0 = password H_n = hash(H_n-1, device unique salt), 1<=n<max_iterations thanks for any insights,s -- otr fp: https://www.ctrlc.hu/~stef/otr.txt _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography
