Abstract

Abstract: Aiming at existent issues of role-based access control delegation model，Role-Task Based Controlled Delegation Model（RTBCDM） and its formalized description are presented，and a simple mode is used to deal with delegation of role’ privilege.This model supports very fine-grained delegation in a dynamic environment，it also supports part privilege’s multiple delegation and task-based task excluded constraint characteristic，the dynamic constraints and general constraints of this model has increased its expression and controllability by the square.

Key words: role based access control, delegation, task, constraints

摘要： 针对目前RBAC委托模型存在的问题，提出了RTBCDM模型及其形式化表述，以一种简单的方式处理角色对其特权的委托。模型支持动态环境下更细粒度的委托，普通约束、动态约束、支持部分特权的多重传递以及基于任务基础的任务互斥约束特性，极大地增强了委托的可控性和模型的表达能力。
