摘　　要：电子文档给办公带来便捷的同时也存在相应的安全隐患,构建以密级划分的多级安全系统,对文档进行多级访问控制是解决电子文档安全的有效方法。本文在研究基于中国剩余定理的多级密钥管理方法基础上,给出了一种电子文档多级访问控制方法,并对该方法的动态性、安全性和实用性进行了分析,最后给出了一个电子文档多级访问控制系统的基本框架。Besides the convenience it brings to office, Electronic documents also have some security risks. Building a muhilevel security system which divided by secret level identification and make a document~ mul- tilevel access control is an effective way for solving the electronic document~ security problems. After the re- search of management of multilevel key based on Chinese Remainder Theorem, this paper not only presents a method about electronic document~ multilevel access control, but also gives an analysis of the dynamic na- ture, safety and practicality. Eventually, the paper designs a basic framework for electronic document~ mul- tilevel access control system.
