Abstract: 

In the recent years, access to ICT has become not only an economic imper-
ative for nations seeking progress, but also an essential asset to improve
the development of societies as a whole. However, still in 2010, more than
90% of the population of Africa has no access to Internet.

The Bytewalla project was started with the objective of narrowing the
global digital divide in Africa, by implementing DTN in Android phones.
This solution is aimed at providing connectivity to places where traditional
end-to-end infrastructure is prohibitively expensive or not scalable.

The thesis work consists on the deployment of a security solution for DTN
in the Android platform. Our solution comprises the implementation of
the Bundle Security Protocol, which will be used in the Bytewalla pro-
gram. We have carried out performance tests to measure size and battery
overhead, and we made a thorough security assessment of the Bytewalla
system.

The fact that our DTN security implementation is compliant with the
Bundle Security Protocol specication has two clear implications. Firstly,
the Bytewalla system will be ready to be deployed in a real world test
bed as soon as security in the DTNRG reference implementation is fully
implemented. Secondly, our compliant implementation can be utilized to
deploy security in any DTN application based on the Android platform.
