摘要

角色授权是角色访问控制模型中一个重要部分

已有形式化方法大都集中在显式的描述上.本文在研究已有的RBAC模型基础上

结合关系数据库水印技术信息隐藏的特点

提出一种基于数字水印的数据库角色访问控制模型及其实现框架

重点研究了与角色授权相关的水印算法

并给出模型在入侵容忍安全数据库模型中的实现.

Abstract

Role authorization is very important in RBAC models.Existing formalized methods focus on explicit description.Based on current RBAC models and associated with information hiding technique of watermarking relational databases

a digital watermark based database model using RBAC (WRBAC) and its framework are provided.Then

digital watermark algorithms about role authorization are emphasized.Finally

implementation of WRBAC model in our intrusion tolerance database environment is provided.
