Providing a secure hierarchy access control system based generated the polynomial

Nowadays, the use of computer systems is increasingly growing. Saving documents electronically, User-friendly, easy access for users is provided. In this situation, security in hierarchical systems organization chart is very important.In this article we provide a Hierarchical access control model that using polynomials to generate access key. The Proposed scheme has low computational and memory overhead. This scheme can use in the large scale.
