The distribution of the remote system hardware in different places makes
legal users access the resource more conveniently and efficiently. Again, backup of the
resource is also an important concern of the scatter. So far, most of the password authentication
schemes are designed for single-server environments, users who want to
access different remote servers need to register many times and keep many accounts and
passwords. To solve this problem, we propose a more efficient version for multi-server
architecture. In particular, the new method employs a time-bound mechanism such that
the remote system can effectively conduct the valid access period for each legitimate user.
