Information System Security Model With Sharing
Translated Abstract
To address the problem of protection and sharing of information, the BLP model of stand-alone computer system was extended to information systems with multi-level security, the principle of need-to- share and the notion of multi-level object was introduced, and a multi-level security model of information system for application was developed. Then, some basic security assumptions were proposed, and the formal multi-level security model of information system was presented. The security model allowed the information to be securely shared with the right people and protected from the wrong people, while maintaining the multi-level security of information system.
