Privacy preservation services: Challenges and solutions

The current Internet architecture was designed at a time when many of the current network applications did not even exist. As a result, it has become increasingly difficult to deploy new and secure services on the Internet. Hence, a new Internet architecture is required to address the security and usability issues that affect the current Internet. In this paper, we examine the current Internet architecture from various security and user perspectives using two privacy services and propose some architectural guidelines and principles for the future Internet Architecture. The two aforementioned privacy services that we chose are: i) anonymous communication services and ii) identity management systems. We examine the challenges in implementing anonymous communication services, and identity management systems and identify the problems with existing solutions for these challenges. Based on the problems identified in the current Internet architecture, we propose a virtualization-motivated set of architectural principles and design rules for the future Internet.
