Abstract: The fundamentals of secure systems can be presentedas the three cornerstones: authentication (trustworthinessof senders), integrity (inability to alter messages) and confidentiality(inability to read messages for anyone except theintended recipient). In this project, an android application hasbeen programmed by the author with the purpose of sendinggeographical data over a bluetooth connection in a secure peerto-peer manner. In the application, the three goals were metprimarily through the use of certificate validation, encryption anddigital signatures. The final application features a user-interfacewith a Google Maps interface, and query parameters that theuser can set when requesting data about a certain position.The final application would very much be considered secure inan environment where only two android devices are communicating.However, more steps would have to be taken if the applicationis to be deployed commercially. The primary questions arescalability, speed and further security complications.
