Secure Connectivity With Persistent Identities

In the current Internet the Internet Protocol address is burdened with two roles. It serves as the identifier and the locator for the host. As the host moves its identity changes with its locator. The research community thinks that the Future Internet will include identifier-locator split in some form. Identifier-locator split is seen as the solution to multiple problems. However, identifier-locator split introduces multiple new problems to the Internet.

In this dissertation we concentrate on: the feasibility of using identifier-locator split with legacy applications, securing the resolution steps, using the persistent identity for access control, improving mobility in environments using multiple address families and so improving the disruption tolerance for connectivity.

The proposed methods achieve theoretical and practical improvements over the earlier state of the art. To raise the overall awareness, our results have been published in interdisciplinary forums.
