一种基于SDL的角色系统描述框架

A SDL-based role system description framework

将SDL(standard deontic logic)引入到角色管理系统,提出一种基于SDL的角色系统描述框架SBDF(SDL-based role systemdescription frame).在该框架中,对系统中的角色进行分类.提供一系列的逻辑谓词,通过对各类角色的操作行为进行规范化描述,从而达到提供系统安全级别的目的.同时,为提高角色行为执行的效率,引入Agent技术,由Agent执行各角色的具体操作,通过对系统进行描述,方便对用户及角色的管理,提高了系统的安全级别.

SDL（standard deontic logic）, as a set of logic reasoning specifications, is introduced to role management system, and a description framework, called SBDF（SDL-based role system descrpion frame） is proposed in the paper. In SBDF, roles are classified, and theirs actions are expressed by a series of predicates. Meanwhile, agents are introduced to perform the actions of all kinds of roles, so as to enhance execution efficiency and security level.
