Abstract
A new access control scheme for implementing the access control matrix is proposed. The proposed scheme is different from the methods which are based on the concept of key- lock pairs. In the proposed scheme, each user is assigned a binary key, which is derived from the access rights with respect to the files. The binary key is possessed by the user, and can be used to derive the access right to the files. The characteristics of the proposed scheme are that the system can protect the files without explicitly maintaining an access control matrix, the derivation of the access rights is simple, and the dynamic access control can be easily achieved.
