Functional and operational security system for open distributed environments

Abstract

The paper describes the design details and implementation results of the completely integrated, functional and operational security system, suitable for open distributed environments. Functionality means that security system provides all ISO/OS/ security services and operability means that the described system is completely operational on various user platforms. The components of the system are smart cards, secure user workstations, integrated security clients, security servers and global certification system for international networks. Several security enhanced applications are also described in the paper: secure PC based on smart cards, secure Internet E-mail (PEM ) and secure EDI, all based on the same concept of the security system, common security architecture and integrated security technologies and products.
