Google no longer requiring encryption on Lollipop devices

lollipop-blog
In the lead-up to the launch of Android 5.0 Lollipop, there was much ado about Google encrypting devices for a higher level of security. At the time law enforcement officials cried foul, with device keys no longer in the hands of Google (or anyone) to unlock data stored on the phone. But it seems that Google has backtracked on the requirement for OEMs to enable ecryption by defualt on new Lollipop devices being launched.

Ars Technica first noticed the difference on newly released Android 5.0 devices arriving in the market. The user partition on the newly released generation 2 Motorola Moto E was not encrypted and when the Galaxy S6 was checked after the launch the other night, they noted that this was also true of these models as well.

Ars Technica points to the change in the Android Compatibility Definition document, the guidelines to which Android OEMs must adhere in order to produce Google-approved devices running Lollipop and found a subtle difference. Previously, in a snapshot taken on October 25th 2014, the Android Compatibility Definition document reads simply :

9.9. Full-Disk Encryption
IF the device has lockscreen, the device MUST support full-disk encryption.

But if you read the current Android Compatibility Definition document this has now been amended to (Note: Emphasis below is Google’s) :

9.9 Full-Disk Encryption

If the device implementation has a lock screen, the device MUST support full-disk encryption of the application private data (/data patition) as well as the SD card partition if it is a permanent, non-removable part of the device. For devices supporting full-disk encryption, the full-disk encryption SHOULD be enabled all the time after the user has completed the out-of-box experience. While this requirement is stated as SHOULD for this version of the Android platform, it is very strongly RECOMMENDED as we expect this to change to MUST in the future versions of Android.

The underlying tone is that as long as OEMs offer the ability to encrypt devices if the user so chooses, that is now good enough now to pass the requirements.

The question of whether the full device encryption requirement has been removed due to the insistence behind the scenes of law-enforcement, from OEM pushback, or even from reports of slow response times on devices like the Nexus 6 when running encrypted systems vs unencrypted is unknown.

This now boils down to a choice for users: if you want your device encrypted then you can enable it, but if you don’t then you will no longer be required to run your device encrypted out of the box – something the average user will most likely not do, to the applause of the NSA and security agencies everywhere.

Dan is a die-hard Android fan. Some might even call him a lunatic. He's been an Android user since Android was a thing, and if there's a phone that's run Android, chances are he owns it (his Nexus collection is second-to-none) or has used it.

Dan's dedication to Ausdroid is without question, and he has represented us at some of the biggest international events in our industry including Google I/O, Mobile World Congress, CES and IFA.

I wish i could easily unencrypt my nexus 6. I personally find it very slow. I’m on the verge of flashing it with custom image that doesn’t encrypt…

I’m holding hope google will include hardware support for encryption in 5.1 update.. but maybe thats wishful thinking.

“MUST support full-disk encryption.” Doesn’t mean must be enabled by default! It just means the device just be able to support it. Google has never had full disk encryption enabled by default across the board in any lollipop release BTW. Yes the nexus 6 had it enabled by default, but that was it. The nexus 4 and 5 and both nexus 7 devices didn’t have it enabled by default. I’m pretty sure if you check the moto g/x phones that got lollipop they didn’t enable it be either. So its not really a change in policy as such its always… Read more »
