	Elena Reshetova: If you use your own kernel, you are the one to set the security policy for the device, meaning that your SW in this case can make calls, send ~~sms~~ and so on (for example). Please note that the list of protected resources on the slide is given just as example (to show the possible granularity level), so it doesn't mean that we would have exactly these resources.

	Elena Reshetova: If your application uses the Protected Storage for encryption (slide 8) in the initial mode, and after you switch to another mode, the application won't be able to get decrypted data. If your application just stores the data in the filesystem, after switching to your own kernel, you will be able to access the data (because they are just plain files in the filesystem).

	===Can open applications use the privilege mechanisms in the Open and Closed modes?===		==Can open applications use the privilege mechanisms in the Open and Closed modes?==

	Elena Reshetova: I guess the question is "Can the applications access protected resources in both modes?" I hope I got the question correctly. The answer is that the Device Security Policy (slide 7) defines the resources can be potentially granted to the SW coming from a particular SW source. When one uses the Nokia signed kernel, the device security policy is defined, and user can't change it. If one uses its own kernel (or community kernel for example), he (or community) is the one to define/change the device policy. This means that one can, for example, change the policy in the way that the SW coming from the maemo.org gets access to all protected resources (of course some content becomes unavailable when one switch to its own kernel, for example DRM). However, again, it is possible only while using your own kernel.		Elena Reshetova: I guess the question is "Can the applications access protected resources in both modes?"
