In this paper we use fuzzy controller for enhancing
the security of password.in our results, also we use fuzzy
controller for preventing of dictionary attack. In this attack
when eavesdropping want to find one password, regardless
of the user ID, if the password is 6 digits, before
eavesdropping want to creates a list of 6 digit number
(000000 to 999999) and then apply the hash function to
every number, it must pass from fuzzy controller because
digits or data should convert to fuzzy data and
eavesdropping cannot create a list of six digits (depending
on the password length) and cannot apply the hash function
to every number and also is not able to convert fuzzy data
to digits or real data. The result of this procedure is raising
password security.
