Role authentication for secure DBMS

Abstract

Public Key Infrastructure(PKI) is the prevalent method of authentication. Privilege Management Infrastructure(PMI) as a new technology can provide the user's attribute information. The main function of PMI is to give more specified authority and a role to the user. And Role Based Access Control(RBAC) is implemented by digital signature. RBAC provides some flexibility for security management. To protect DB from hacking, we propose a secure DBMS using this PMI and RBAC. Application of DB encryption can be one of key technologies for contents protection. In this paper, we have applied the access control based on RBAC to prevent the unauthorized users from gaining access to contents and propose a new DB encryption scheme which uses RBAC and digital signature based on PMI.
