Cryptophone as source for new ideas

Added by karman man over 9 years ago

Hey,
are the Replicant Devs aware of the Cryptophone Company? They claim to have a hardened Andoid version on their Cryptophone 500 [1]. Which is basically an modified Galaxy S3. It is possible to get their source code here [2]. Even if its not allowed to use it directly it may be a source for new ideas. The Galaxy s3 is even a Replicant supported device, which makes this more interesting :)

Thanks for that hint, I was not aware of that company.

I personally don't think the Replicant project will benefit too much from that software with that license terms:
http://www.cryptophone.de/en/background/source-code/license/

I just spent a very short look; but I think the feature-list (Source: http://www.cryptophone.de/en/products/mobile/cp500/) could be enabled with open source software apps on Replicant, too:
  • "Secure messaging and voice over IP calls on any network [...]"
    You could try:
  • "Hardened Android operating system with granular security management [...]"
    Check out some do it yourself hardening
  • "Permission enforcement module controls access to network, data and sensors, keeping you in control of your security policies"
    This sounds like:
  • "Baseband firewall protects against over-the-air attacks with constant monitoring of baseband processor activity, baseband attack detection, and automated initiation of countermeasures"
    I think you could get the same result if you use the:
  • "Two-layer storage encryption system protects data at rest against unauthorized access"
    If you have encrypted your device (Settings -> Security -> Encrypt phone), you get a second layer of storage encryption, if you:
    • additionally encrypt files with OpenKeychain
    • and/or contents of apps (like password managers or encrypted notepads to).
    • Finally, don't forget email encryption. Just use K-9 Mail combined with OpenKeychain from above.

(Of course the named apps are just examples. There exists some more alternatives with similar features. Just have a look at your own)...
