Nuno Azevedo defends master dissertation entitled "Service and auto-configuration framework for secure ad-hoc environments in Android and Linux"

Nuno Filipe Solinho de Azevedo has requested the defence of his dissertation, entitled "Service and auto-configuration framework for secure ad-hoc environments in Android and Linux". The defence will be held in room A2 of the Departamento de Informática, on December 20, 2011, 11:00am. The public is invited.

The examining committee is the following:

  • João M. Fernandes (UMinho) - president
  • Jorge Sá Silva (UCoimbra) - opponent
  • António Costa (UMinho) - supervisor

Abstract

Ad-hoc networks can be useful in many contexts because they can be spontaneously created and do not require any sort of infrastructure. They can be useful for small groups when no other network is accessible. They can also be used in wider areas as a low cost replacement for wireless infrastructure networks with multiple dedicated access points. Despite this, ad-hoc networks are not a very popular option for most users.

Unfortunately, ad-hoc networks are not as user friendly as infrastructure networks. The latter ones usually provide standardized mechanisms that perform the essential configurations for the correct functioning of the network. Ad-hoc networks do not have standardized mechanisms adapted to them. Each wireless network manager supports a different set of configuration mechanisms. There is usually no problem when every machine uses the same operating system but when different ones are used, users may need to manually perform the required configurations. Another cause for this low popularity is the lack of useful and easy to use applications. These applications are usually hosted on the Internet, as it provides a larger variety of business models.

To tackle these problems, new forms of automatically configuring machines and providing services should be explored. These services must be easy to develop, in order to attract the developers that would develop them. The designed solutions must also be adapted to ad-hoc environments. Another important aspect that must be addressed is security. In some contexts, such as public and corporate environments, security can be essential to provide authentication and even to allow the correct functioning of the
network.

In this work, a functional framework that addresses these problems is designed and implemented. The framework is capable of automatically making the necessary
configurations to provide a functional and secure ad-hoc environment. It is also capable of hosting specialized and easy to develop services, over the spontaneously created
secure environment. The developed framework is easy to use and was throughly tested in Android and Linux, but it can be easily extended to work in many other operating
systems.
