A Trust-based Secured Performant Funnel Mobile Service Discovery and Exposure Model

IMS (IP Multimedia Subsystem) is subject of various evolutions and refinements. Guideline of these improvement is to upgrade subscriber experience by proposing services and features that respond to its requirements. These features include different actors namely, operators, service providers and subscribers. Through such networks, an important mass of information exists. Many exchanges and interactions are performed between actors. Information, and especially sensitive ones, may be target of malicious attacks. Thus, ensuring actors identity and securing information exchanges through networks remains necessary. Network performance should not be deteriorated at the expense of security aspect. This paper presents our Trust-based Secured Performant Funnel based Mobile Service Discovery and Exposure Model to get around the presented problematic with optimization metrics to avoid network performances deterioration. Results shows improvement compared to other works on several axes.
