| - | Suggested questions:
| + | == This is now at [[Talk:Maemo security]] == |
| - | | + | |
| - | ===Is there a diagram showing the security framework and components?=== | + | |
| - | There were some diagrams in the presentation - can we see them.
| + | |
| - | | + | |
| - | ===What is "Open Mode" and can it be revoked remotely?===
| + | |
| - | Is that the right terminology?
| + | |
| - | Essentially can Nokia reach out the the 2nd stage bootloader and tell it to stop running unsigned kernels.
| + | |
| - | Maybe this should be 2 questions.
| + | |
| - | | + | |
| - | ===What does closed mode restrict you from doing? Terminal? Root?===
| + | |
| - | | + | |
| - | ===How easy is it to switch between Open and Closed modes?===
| + | |
| - | | + | |
| - | Is it so trivial that you would want to and be able to do it several times a day and on the go (without restart)?
| + | |
| - | | + | |
| - | ===Can network operators restrict you switching to Open mode?===
| + | |
| - | Like if a device is sim-locked to a particular network, does the device get locked down in closed DRM mode only too? Can you always switch to open mode?
| + | |
| - | | + | |
| - | ===How granular is the encryption?===
| + | |
| - | If my app creates content in the closed mode can I see it in open mode?
| + | |
| - | | + | |
| - | ===Can open applications use the privilege mechanisms in the Open and Closed modes?===
| + | |
| - | | + | |
| - | ===Can open applications use the DRM encryption mechanisms in the Open and Closed modes?===
| + | |
| - | I can see that this could be useful. Maybe.
| + | |
| - | | + | |
| - | ===Will community extensions to the kernel (modules) be permitted in Open/Closed modes?===
| + | |
| - | I can't see how - which leads to the question: How do community 'enhancements' to the kernel get adopted?
| + | |
| - | | + | |
| - | ===Is there any GPLv3 software impacted?===
| + | |
| - | Please have a license discussion somewhere and let us know when you have consensus.
| + | |
| - | What is Nokias position? Peter made a statement at the talk - can someone transcribe it and/or get Nokia to clarify.
| + | |
| - | | + | |
| - | ===What exactly is available to the end user?===
| + | |
| - | | + | |
| - | * storage encryption ?
| + | |
| - | * PIM data encryption ?
| + | |
| - | * encrypted/signed communications (phone, sms/mms, mails, IM) ?
| + | |
| - | | + | |
| - | === How does closed mode affect on-device debugging? ===
| + | |
| - | | + | |
| - | For example, will ptrace(2) still work (eg gdb, strace & ltrace)? Will we be able to produce code dumps?
| + | |
| - | | + | |
| - | ===Will DRM-free data and DRM-free applications be accessible from both modes once they're installed/created in either of the two modes?===
| + | |
| - | | + | |
| - | E.g.: I start in DRM-mode, install DRM-free applications from Extras, take 3 pictures, add some contacts. Then I switch to DRM-free mode: Will I be able to run the applications installed in DRM-free mode, view and edit my contacts and view and edit my own pictures? (And the other way round, of course, starting from DRM-free mode and switching to DRM afterwards.)
| + | |
| - | | + | |
| - | ===What is open mode good for at all?===
| + | |
| - | | + | |
| - | Provided you don't consume digitally restricted media and don't purchase applications that in any way rely on DRM: You don't need DRM-mode then, but on the other hand why would you want DRM-free mode? What is it you cannot do in DRM-mode in such a scenario? Use case?
| + | |
| - | | + | |
| - | ===What is ARM's TrustZone?===
| + | |
| - | | + | |
| - | ===Can the Trusted Execution Environment (TrEE) be used as a kill switch for the device even if it runs in open mode?===
| + | |
