Background
The main use of the Internet today has shifted toward distribution of content. New Internet architecture designs are underway to rethink how content should be distributed and stored in the Internet. One promising approach is Information-centric Networking (ICN), a candidate of next generation Internet architecture. The main idea of ICN is to support content-based data dissemination through in-network caching and request-based content retrieval. Data objects can be cached in ICN routers, this way the requests can be served directly from the router caches and not only from the original source. This architecture design is different from traditional host-based end-to-end communication. It is more scalable and efficient in the distribution of data objects.
Description
This thesis work is intended to combine and extend three previous thesis works. Two of the previous works have already been integrated into a network solution for disaster scenarios. It is aimed at distribute cached information in the network in such a way that when network connectivity breaks (unexpectedly) and partition the network, most data will still be available in the fragments of the network. This is achieved by predicting were the network might fragment and making sure that each fragment has a Content Tracker (CT) that tries to make sure that relevant data is stored within the fragment.
The third thesis work is about the use of Attribute Based Encryption ABE) for access control.
The task of this thesis work is to introduce and implement the ABE based access control in the disaster ready ICN network and evaluate it compared to other access control mechanisms such as group key encryption or token based access control systems.
ICN decouples data from the source and allows data objects to be stored anywhere. To allow storing data on untrusted nodes and transporting it over untrusted links ICN relies on object security. When multiple access groups shall have access to the same data object it is a big advantage if it is not necessary to encrypt the same object multiple times. ABE can support complex access policies that make it possible to encrypt the data object only once.
Objectives:
In ICN each node has a cache where it can store information objects. This means that objects can be made available to other users at a later time, even if the original source is no longer available or offline. In a disaster scenario where no infrastructure is available this makes all nodes capable to function as “data mules”. To be able to find data that might be stored on some nearby node. There are several challenges to achieve this. If time permits some of these challenges might also be part of the thesis work.
The main goal of this thesis work is to introduce and implement the ABE based access control in the disaster ready ICN network and evaluate it compared to other access control mechanisms such as group key encryption or token based access control systems. The work will be carried out in a number of phases.
