Development of the android-based secure communication device

The possibility of secure communication used only to be the privilege of professional services and systems which could afford to allocate enormous funds for the development of specialized communication devices. Nowadays, through the popularization of the open-source development model, significant reduction of development costs was thus enabled, together with maintaining a high level of security. Such development implies the inclusion of ready-made components, the operating principles of which may be checked and modified, when needed. This paper shall elaborate on key issues concerning the development of mobile devices for secure communication based on the Android platform.
