Nowadays, most applications are transaction
processing which are installed on enterprise server. Server has to
examine if client’s requests are authentic users or not. Most
applications ask for login name and password of each user. After
user’s sending his login name and password, there were used to
seek for correction whether it is appeared in client login name
and password table or not. If there is found then server permit
client to access application program. There are many problems
happened in this situation such as password copying by intruders
and server responsibility in password table serious keeping. This
paper present a simplify login protocol which could be
implemented easily. Intruder could not copy user’s password
which was sending through networking. Server still has to keep
user’s properties in secret but user’s password may be arbitrarily
and changed frequently subject to server preference.
Performance of this protocol consume a little bit of
computational time so that it should not bother user too much.
