%X This paper proposes a new mechanism for access control based upon Euler' s theorem. With this mechanism,once access privileges of object are assigned to subjects,then the locks and keys, corresponding to the objects and subjects, respectively, can be decided automaticaly. And when an access attempt is made,the subject access right upon an object c:an attained by simple cal-culation with his key and its lock without retrieving any table. So it is a reasonable access control method.
