摘要 基于角色的转授权模型 (RDM )适于分布式环境下的授权管理 在分析重复角色转授权 (RRD)和部分角色转授权 (PRD)的实质和必要性的基础上 ,提出了基于重复和部分角色的转授权模型 (RPRDM ) ,并定义了该模型的组成元素以及转授权和转授权撤销规则 最后 。 Role based delegation model (RDM) is more suitable for delegation in distributed environments First, the essence and necessity of repeated role delegation (RRD) and part role delegation (PRD) are analyzed Then, a repeated and part role based delegation model (RPRDM), a new RDM, is presented, and the model's definition and delegation/delegation revocation rules are given Finally, a prototype of RPRDM on Linux is implemented
