摘　　要：本文提出一种基于logistic映射数字流混沌加密的权限管理方案,并应用于《基于logistic映射数字流混沌的信息加密软件》中。该权限管理方案解决了不同的用户具有不同的权限等级,不同等级权限的用户具有不同的阅读文件的权限。对于某一文件,如果用户不具有查阅或修改的权限,那么就不能解密该文件,实现了文件的分级保密。A implementation of classified rights management scheme is proposed in this paper, it was used in Encryption software based on logistic mapped digital stream chaos. In this scheme, different person own different rights, then , different employees or employers can access different files. Whether they can access the file depended on their rights, such as to access or modify it ,it can not decrypt the file if they are not own the rights, we realized how to keep secret on files classificatorily.
