Authentication And Key Agreement

Next Generation Networks (NGN) is the evolution of the telecommunication core. The user has to execute multi-pass Authentication and Key Agreement (AKA) procedures in order to get access to the IP Multimedia Subsystem (IMS). This causes overhead on the AAA server and increases the delay of authenticating the user and that is because of unnecessary and repeated procedures and protocols. This paper presents an enhanced one-pass AKA procedure that eliminates the repeated steps without affecting the security level, in addition it reduces the Denial of Service (DoS) attacks. The presented mechanism has minimal impact on the network infrastructure and functionality and does not require any changes to the existing authentication protocols.

Kommunikationsnetzbetreiber suchen aufgrund der kontinuierlichen Preiserosion nach neuen Umsatzquellen. Neben den Perspektiven mobiler Datendienste setzen sie auf die Möglichkeiten neuer Kommunikationsnetze unter dem Schlagwort Next Generation Networks (NGN), um unter anderem die Servicequalität (Dienstgütequalität) definieren zu können. Hierzu müsste allerdings die bestehende Netzneutralität, die eine diskriminierungsfreie Übermittlung von Daten sicherstellt, abgeschafft werden. Diese Ambitionen stellen für Google eine signifikante Bedrohung seines Geschäftsmodells und seines unternehmerischen Erfolgs dar. Google hat in den letzten Jahren mit verschiedenen Investitionen, Beteiligungen und Akquisitionen auf der Ebene der Infrastruktur, der Endgeräte und der Anwendungen auf diese Bedrohung reagiert. Dabei handelt es sich nicht nur um eine reine Konterstrategie, sondern Google versucht damit, sein erfolgreiches Geschäftsmodell auf die Telekommunikation und hier insbesondere auf die Mobilfunknetze auszudehnen. Im Erfolgsfall könnte dies signifikante Veränderungen im Geschäftsmodell der Telekommunikationsunternehmen zur Folge haben.

Using JAIN SLEE as an Interaction and Policy Manager for Enabler-based Services in Next Generation Networks The IP Multimedia Subsystem is a telecommunications framework with a standard architecture for the provision of services. While the services themselves have not been standardised, standards do exist for basic technologies that can be re-used and aggregated in order to construct more complex services. These elements are called service capabilities by the 3GPP and service enablers by the OMA, both of which are reputable standards bodies in this area. In order to provide re-usability, there is a need to manage access to the service capabilities. Also, in order to build complex services, there is a further need to be able to manage and coordinate the interactions that occur between service capabilities. The 3GPP and the OMA have separately defined network entities that are responsible for handling aspects of these requirements, and are known as a service capability interaction manager (SCIM) and a policy enforcer respectively. However, the internal structure of the SCIM and the policy enforcer have not been standardised by the relevant bodies. In addition, as the SCIM and the policy enforcer have been defined through complementary yet separate processes, there is an opportunity to unify efforts from both bodies. This paper builds on work and standards defined by the bodies, and proposes the design of an interaction manager with features borrowed from both the SCIM and the policy enforcer. To help validate the design, we have identified a platform known as JAIN SLEE which we believe conforms to the model proposed, and we discuss how JAIN SLEE can be used to implement our ideas.
