Abstract

This paper describes techniques and solutions for management of groups and cryptographic keys when sharing secure documents protected at different classification levels. Such access control environment enforces access to documents at multiple security classification levels, starting from the membership in the group, then access to particular group applications, then access to individual documents and finally even their sections.
