This dissertation was written as a part of the MSc in Mobile and Web Computing at the International Hellenic University. The Internet of Things (IoT) is taking advantage of the Internet and other wireless technologies to make physical objects interact online. It is a promising technology and receives research and public attention in the recent years. IoT is still very young and despite the inevitable progress in the field, it contains privacy and security risks. Researches and applications of the IoT are in an early stage and to preserve peoples’ privacy, the security of IoT must be strengthen. Following this path, this thesis proposes the use of a Raspberry pi as a security counter-measure. The Raspberry pi acting as a server, an access point and a role base model secures the communication between an android application and the sensors attached to it. Giving the opportunity to a mobile application to handle any kind of device attached. To demonstrate the proposed technique, a mobile application will be developed, a software component on the Raspberry pi to support the mentioned functionalities and also hand-made printed circuits boards to simulate simple sensor functionalities. At this point I would like to thank my supervisor, Dr. Christos Kalloniatis, for the encouragement, motivation, enthusiasm, guidance and advice he has provided in all time of re-search and writing of this thesis. I have been extremely lucky to have a supervisor who cared so much about my work, and who responded so promptly to all my questions and queries.
