Sicheres Verfahren zur Autorisierung und zum Accounting von Ressourcenreservierungen in All-IP-Netzen

  • Description

    All-IP-based networks are nowadays commonly used especially for so-called Next Generation Networks, in order to provide services for telephony, file tranfer, or video distribution. In order to use these services a service provider must be able to authenticate a user, check if he or she is authorized to use these services, and finally account the user properly (AAA: Authentication, Authorisation, and Accounting). The Next Steps in Signaling (NSIS) framework was specified within the IETF in order to provide network signaling protocols for the Internet, e.g., to establish Quality-of-Service (QoS) resource reservations or to dynamically configure NAT gateways and firewalls.


    The main goal of this thesis is to design and implement concepts that allow a proper interaction between the NSIS signaling protocols and existing AAA protocols, such as EAP or Diameter.
