Microsoft OneDrive in NSA PRISM


A sends:

1) Bitlocker keys are uploaded to OneDrive by 'device encryption'.

"Unlike a standard BitLocker implementation, device encryption is enabled automatically so that the device is always protected.

...

If the device is not domain-joined a Microsoft Account that has been granted administrative privileges on the device is required. When the administrator uses a Microsoft account to sign in, the clear key is removed, a recovery key is uploaded to online Microsoft account and TPM protector is created."

2) Device encryption is supported by Bitlocker for all SKUs that support connected standby. This would include Windows phones.

"BitLocker provides support for device encryption on x86 and x64-based computers with a TPM that supports connected stand-by. Previously this form of encryption was only available on Windows RT devices."

3) The tech media and feature articles recognise this.

"... because the recovery key is automatically stored in SkyDrive for you."

4) Here's how to recover your key from Sky/OneDrive.

"Your Microsoft account online. This option is only available on non-domain-joined PCs. To get your recovery key, go to ...onedrive.com..."
