摘要： 结合计算机支持的协同设计(CSCD)系统的具体特点,对角色委托授权(RDA)特征进行分析和归纳,并给出CSCD系统的RDA特征集表示·由于不同系统具有不同的RDA特征集,导致不同系统的RDA模型也具有各种不同形态·在介绍RBAC基本模型的基础上,归纳出几种基本的RDA特征,并根据CSCD系统的具体特点对RDA特征进行组合,从而建立起适合CSCD系统的RDA模型·与传统的RBAC角色授权模式不同,该模型将权限的集中方式管理分散实施,使权限管理更加灵活方便·最后通过CSCD系统实例对上述RDA模型进行了验证·

Abstract: According to the definite characteristics of the computer-supported cooperative design (CSCD) system, the characteristics of role delegation authorization (RDA) were analyzed and deduced, and a set of fitful status was found out. Because of the diversified characteristics of RDA features in different systems, the RDA model has multi-varying status. Introducing the basic model of role-based access control (RBAC), some basic characteristics of RDA was summed up. Then, the characteristics of RDA were recombined together according to the definite characteristics of CSCD system to develop a RDA model that is adaptable to CSCD system and different from the conventional role authorization models of RBAC, i.e., takes up the decentralized authorization management instead of centralized one in CSCD system to make it more flexible. This RDA model is verified through a CSCD example.
