Security Enhanced Mobile Operating System (SEMOS)

The Security Enhanced Mobile Operating System, or SEMOS for short, is a project being designed for a Samsung Galaxy Nexus, running Android 4.3.x. The device will be using an Operating System (OS) that is tailored specifically for heightened security. Tungsten Industries is the sponsor for the project, and would like to create a platform for Android based devices that delivers the security and control a user ought to have.

Starting from an Android core OS, based on the Android Open Source Project (AOSP) with SELinux, we will determine the feasibility of a secure mobile operating system. Our current goal is to study and implement three specific research topics: Mandatory Access Controls (MAC) using Multi-Category Security, Automated Encrypted Cloud Storage, and Remote Service Log Checking & Retrieval. Long term we wish to create a stable, secure, mobile OS with a sleek and easy to use interface. And all while assessing project risks and providing a status reports to the end of the semester.

Project Goals

 * At the start:
 * Research how feasible as well as the process to obtain the following on an Android Mobile Device:
 * Encrypted Data Storage
 * Remote Service Log Retrieval
 * Permission Policy Management
 * Create a GUI application for Permission Policy Management


 * Current project goals:
 * Continue original research
 * However, a greater portion of the project focus will shift to permissions policy management and application construction
 * Expand and refine the current GUI application
 * Develop an IDE for policy building
 * Test MAC and Policy Manager on a physical device
 * Focus on application interaction and stability

Design Specifications
Expanding on the current goals outlined above.


 * Continue Original Research
 * Determine the best manner in which to port the encryption function from user to kernel level
 * Monitor AppOps progress and the community's response
 * Look further in to creating and optimizing permission policies
 * Expand and refine the current GUI application
 * Establish toolbar functionality
 * Add toolbar search and settings features
 * Add logic for handling larger than normal application icons
 * Add additional aesthetically pleasing features
 * Develop an IDE for policy building
 * Design the application
 * Implement it's core features
 * Integrate it into the Policy Manager GUI
 * Test MAC and Policy Manager on a physical device
 * Ensure the application doesn't take up an unnecessary amount of system resources
 * Determine how well other applications hold up during general use with the Policy Manager GUI and permissions in effect

Policy Manager Development

 * Screen 1 main components complete
 * Need to fully implement the toolbar
 * Add search functionality
 * Add in settings
 * Screen 2 main components complete
 * Add in settings
 * Complete human readable policy display
 * Being worked on until mid/late December
