Authentication and authorization in multilevel security systems for public administration

摘要

The article contains a brief survey of the different approaches to authentication and authorization in distributed systems and the new concept of the authentication and authorization based on multilevel security features. Proposed idea should be particularly useful in public administration systems. Such systems can consist of many separated subsystems with completely different authentication mechanisms. The goal of the paper was to develop a prototype of Authentication and Authorization System (AAS in short) to supervise access to the data applications operating in the information systems of public administration.
