In this paper, we present a password stretching method based on user specific salt. Our scheme takes a similar time to stretch a password as a recent password stretching algorithm, but the complexity of pre-computation attack increases by 10^8 times and also the storage to store pre-computation result increases by 10^8 times over a recent password stretching algorithm.
