Embedded Devices Security

To secure the devices embed with the application software’s which can works with desktop or laptop computers. This concept was come from the feedback of the manufacturers that, the software’s are pirated from onsite devices and they are try to manufacture the device.



Idea:
All the micro controllers have built in EEPROM’s , so we can easily store the encrypted serial number of the device which is tested ok.
How can we store the serial number every time while we are using the unique hex files? We can finish this by a special application software which should communicate with the controller, it should incorporate the below steps
1. Software must be the kind Quality and test report generator.
2. First the software should have the ability to program the serial number of the device.
3. After finishing the testing of a device, the report should be update in a database.
4. The serial number should be unique (the database should have to increment automatically when we finished testing.
5. Should be like a test and inventory control database software.
