An integrated One-Time-Password and access control authentication scheme

One-Time-Password authentication is a simple, little cost and more efficient technology. Access control is another mechanism by controlling access which is legal or not. These two are separate. To get high safety and reduce the complexity of operating, this paper proposes a new integrated scheme base on them. It has some important merits include:(1)there is no verification table;(2)users can freely choose and change their passwords;(3)it provides mutual authentication between the user and the server.
