Security Testing of the Communication among Android Applications

摘要

An important reason behind the popularity of smartphones and tablets is the huge amount of available applications to download, to expand functionalities of the devices with brand new features. In fact, official stores provide a plethora of applications developed by third parties, for entertainment and business, most of which for free. However, confidential data (e.g., phone contacts, global GPS position, banking data and emails) could be disclosed by vulnerable applications. Sensitive applications should carefully validate exchanged data to avoid security problems. In this paper, we propose a novel testing approach to test communication among applications on mobile devices. We present a test case generation strategy and a testing adequacy criterion for Android applications. Our approach has been assessed on three widely used Android applications.
