  Abstract

The Secure OS is an operating system which adds security functions to the existing operating system, in order to secure a system from security problemas originated from ingerent frailty of applications or operating systems. With the existing Secure Oses, it is difficult to set an effective security policy securing personal resources in a multi-user environment system. To solve this problem, in this paper we present two Techniques to secure user data efficiently in the RBAC-based Secure OS for a multi-user environment. Firstly we utilizes object's owner information in addition to object's filename. Secondly we make user of meta symbol('*'), which is able to describe multiple access targets. In addition this paper giveas some examples to show advantages from these techniques. And these features are implemented in an solaris-based Secure OS called Secusys.,
