Many people possess mobile phones, sending e-mails and messages on them, sharing pictures and information about themselves and using many applications. However, these people mostly haven’t got any idea whether their personal data are secure or not, and to what dangerous extent their information is at risk when they send it through a data communication channel.
Android smartwatches have been just released last summer. These devices very often need to communicate with paired smart phones - the question is, how these watches can do it and how secure is the data against the eavesdropping attacks over the insecure communication channels.
In this thesis, my aim is to examine and try to give an answer for the issues. These are questions which need to be treated by every developer who wants to develop an application which users can handle without fearing of their personal data getting into the wrong hands.
The proof of the pudding is in eating it, so I developed an application which stores passwords both on mobile phones and watches in a secure way and transmits data through the devices safely in order to demonstrate whether these security problems can be solved.
