Flexible Authentication Framework

The paper deals with the area of user authentication. This service is fundamental for present networks and their security so we start with modern AAA (Authentication, Authorization and Accounting) protocol analysis. As a result of current state and protocol analysis we identify main problems in the field of user authentication - insufficient flexibility and therefore lack of security. These properties are demanded by modern convergent networks which combine wireless networks with cable networks and PLMN (Public Land Mobile) networks. To support the trend of a new device inclusion we increase the flexibility of nowaday solutions by a universal framework introduction. This framework simply works as a tool for a proper protocol choice for a wide spectrum of devices. By this flexibility improvement we are now able to support more devices from sensors to servers without security violations. The framework is also practically shown on a RADIUS example which gives basic conception for future implementation.
