摘要: A new mechanism used for controlling the access requests in information systems is proposed. In our scheme, each access privilege associates to a recursively generated function based on Newton's interpolating polynomial. The insertion of a new user/file into the system and deletion of an old user/file from the system can be easily implemented. Besides, the updating of a privilege of a user to a file can also be successfully implemented without reconstructing all associated functions.
