Google details Android 6.0 requirements: Disk encryption by default …

20 Oct 2015 | Author: | No comments yet »

An Update to Nexus Devices.

Google has updated its Compatibility Definition document for Android 6.0, which essentially tells phone and tablet makers what they need to properly run the company’s latest and greatest operating system. For example, the “Application Sandbox” model keeps applications running separately from other apps and the rest of the device to keep your data safe.Back in April, Google announced Project Fi, its very own wireless network that requires no contract, has no termination fees, and even refunds unused data. There are at least three highlights worth pointing out: Android 6.0 requires that manufacturers enable full-disk encryption by default, what exactly fingerprint sensors require, and Doze mode cannot be modified. With Verify Apps, over 1 billion devices are protected via Google Play, which conducts hundreds of millions of antivirus-like security scans of devices per day seamlessly in the background.

Well, according to the official Project Fi Twitter, free instant invites are available for the next 24 hours to celebrate the shipment of the new Nexus 5X. Also, Android is open source so that anyone can comb through the code to identify and address potential security risks, which makes the platform stronger.

In fact, the Android Security Rewards Program financially rewards security researchers who invest their time and effort in helping make Android more secure. It’s 5.7 inches, WQHD (2560 x 1440) AMOLED display, Gorilla Glass 4, and sports something Google calls “fingerprint and smudge-resistant oleophobic coating.” Welp.

We believe the combination of these approaches has led to there being fewer than 0.15% of devices with any kind of potentially harmful app installed, as long as apps were installed from Google Play. (See more of our research.) An additional approach to further increase the security of Android users involves updates to the device software. For the past three years, we have been notifying Android manufacturers every month through bulletins of security issues so that they can keep their users secure. The company then backpedaled and decided to “strongly recommend” encryption, though it promised to change that to a requirement in future versions of Android. After completely failing the first time we reviewed it, Project Fi proved itself a a worthy, low-cost competitor to the big huge megacarriers in a follow up.

For device implementations supporting full-disk encryption and with Advanced Encryption Standard (AES) crypto performance above 50MiB/sec, the full-disk encryption MUST be enabled by default at the time the user has completed the out-of-box setup experience. The first security update of this kind began rolling out today, Wednesday August 5th, to Nexus 4, Nexus 5, Nexus 6, Nexus 7, Nexus 9, Nexus 10, and Nexus Player. If a device implementation is already launched on an earlier Android version with full-disk encryption disabled by default, such a device cannot meet the requirement through a system software update and thus MAY be exempted.

A lockscreen is still not required, but if a user decides to start using one, this change means it is now no longer necessary to re-encrypt the whole disk. You can use your fingerprint to unlock your device, authorize transactions in the Google Play store, sign into third-party apps, and check out with Android Pay. Is STRONGLY RECOMMENDED to have a false rejection rate not higher than 10%, and a latency from when the fingerprint sensor is touched until the screen is unlocked below 1 second, for 1 enrolled finger. MUST have a hardware-backed keystore implementation, and perform the fingerprint matching in a Trusted Execution Environment (TEE) or on a chip with a secure channel to the TEE. MUST prevent adding a fingerprint without first establishing a chain of trust by having the user confirm existing or add a new device credential (PIN/pattern/password) using the TEE as implemented in the Android Open Source project.

How exactly this will impact phones and tablets that upgrade to Android 6.0 remains to be seen, though it shouldn’t take more than re-scanning your fingerprint. Last but not least, Doze mode is meant to make your device use fewer resources when left unattended: It automatically goes into a deep sleep state to conserve power. That said, even if you forget to plug in your phone before bed, your phone’s alarm clock will still ring (assuming your battery doesn’t completely run out).

Our own Greg Kumparak referred to that device as “cumbersome.” While I feel like the 6P’s “heft” could turn some folks off, I wouldn’t call it a roadblock. Founded in 1998 by Stanford Ph.D. students Larry Page and Sergey Brin, Google today is a top web property in all major glob… read more » Nobody really knows why Google gets involved in phone-making. One of the newest set of Nexus phones, the Nexus 6P, is a premium model starting at $499, so Google may even be trying to apply price pressure to expensive devices like the iPhone 6s Plus, which starts at $750. The other new Nexus, however — the $379 LG Nexus 5X — does fit neatly into the $400-or-less price range that’s become the standard for new Android phones (many phone makers are coming around to the belief that competing with Apple in the premium price ranges is a losing proposition). There is, however, a lot of room at the top and bottom of the phone for the microphone and speaker grills and the front camera sensors — too much room in my opinion.

The resolution of the photos I shot with the 6P’s 12.3-megapixel rear-facing camera seemed equal to that of the photos I shot with the 12-megapixel camera on my iPhone 6s. The 6P’s display makes the Android interface look clean and spacious, and you get the feeling that moving around and organizing content is fast and easy. The phone was fully charged at noon on Friday, and while I watched very little video and played games for only 15 minutes or so over the weekend, the thing didn’t completely out of gas until about 8:30 on Sunday night.

Pain like that can make you philosophical: It made me reexamine the role these powerful little devices play in our lives — it may be too big for our own good.
