A BINARY ACCESS-CONTROL METHOD USING PRIME FACTORIZATION

Based on binary coding and prime factorization, an improvement of the single-key-lock method for access control is presented. In our method, each accessor is associated with a key and each resource is associate d with a lock vector. Through simple mathematical operations on the co rresponding key and lock vector, the system can easily verify the acce ss right for an accessor with respect to the referenced resource. Furt hermore, by our improvement, the system can easily handle the dynamic access control problem, such as adding/deleting accessors or resources , without much effort. (C) Elsevier Science Inc. 1997.
