SWOT analysis is performed on IMS security authentication schemes to demonstrate the effectiveness of each schemes in terms of multiple parameters and associated dependencies for users and network operators. Due to SWOT tool we have been able to describe strengths, weakness, opportunities and threats in each authentication scheme separately. The analysis performed mostly based on the state of art studies, SWOT tool itself approximates authentication schemes but in the discussion chapter we illustrated clearly what is necessary to adopt individually between Non SIM and SIM base authentication schemes. It will help MOBICOME project and network operators to choose the most appropriate authentication technology/ technologies for design and implementation.

In this thesis we have accomplish SWOT analysis of IMS security authentication schemes for IMS network services. SWOT analysis for IMS security authentication schemes are divided into two main categories i.e. SIM based authentication and Non SIM based authentication. Analysis results provided strengths, weaknesses, opportunities and threats about an individual authentication scheme. The selection of authentication scheme is important for design and development within the MOBICOME project. SWOT analysis tool itself exhibit necessary information for advantages and disadvantages. The study holds significance, because of IMS deployment in the FMC environment to achieve seamless access to the services. The goal of the thesis was achieved by defining and selecting the most appropriate authentication schemes after conducting SWOT analysis in Chapters 5 & 6.
