Google has delayed its Android encryption plans because they're crippling people's phones

Google has delayed its Android encryption plans because they're crippling people's phones | IT Support and Hardware for Clinics | Scoop.it

Google is delaying plans to encrypt all new Android phones by default, Ars Technica reports, because the technical demands of encryption are crippling people's devices.

Encryption slowed down some phones by 50% or more, speed tests show. 

In September 2014, Google — along with Apple — said that it planned to encrypt all new devices sold with its mobile OS by default. This means that unless a customer opted out, it would be impossible for anyone to gain access to their device without the passcode, including law enforcement (or Google itself).

This hardened stance on encryption from tech companies came after repeated revelations about the NSA, GCHQ and other government spy agencies snooping on ordinary citizens' data.

Default encryption has infuriated authorities. One US cop said that the iPhone would become "the phone of choice for the paedophile" because law enforcement wouldn't be able to access its contents. UK Prime Minister David Cameron has floated the idea of banning strong encryption altogether — though the proposal has been slammed by critics as technically unworkable.

Apple rolled out default-on encryption in iOS 8 back in September. Google's Android Lollipop system was first released in November — but because the phone manufacturers, rather than Google itself, are responsible for pushing out the update, it can take months for a new version of the OS to reach the majority of consumers.

But as Ars Technica reports, Lollipop smartphones are now finally coming to the market, and many do not have default-on encryption. So what's the reason? The devices couldn't actually handle it.

Speed tests show that even Google's flagship phone, the Google Nexus 6, suffers serious slowdown when encryption is turned on. A "random write" test measuring writing data to memory showed that the Nexus 6 performed more than twice as fast with encryption switched off — 2.85MB per second as compared with 1.41 per second with it on. The difference was even more striking in a "sequential read" test to measure memory reading speeds. An unecrypted device achieved 131.65MB/s; the encrypted version managed just 25.36MB/s. That's a third of even the Nexus 5, the previous model, which came in at 76.29MB/s.

As such, Google is now rowing back on its encryption stance. Its guidelines now say that full-disk encryption is "very strongly recommended" on devices, rather than the necessary requirement promised. Users can still encrypt their devices (even if it slows them down), but it won't happen by default.

Google says it still intends to force it in "future versions of Android".

Apple’s Activation Lock Leads To Big Drops In Smartphone Theft Worldwide

Apple’s Activation Lock Leads To Big Drops In Smartphone Theft Worldwide | IT Support and Hardware for Clinics | Scoop.it

The temptation of a smartphone for a thief is dropping, thanks to Apple’s decision to implement a remote kill switch via Find My Phone that can erase and disable a phone once it’s been stolen or gone missing. A new report from Reuters found that iPhone theft dropped by 50 percent in London, 40 percent in San Francisco and 25 percent in New York. The drops represent theft activity as measured during the 12 months following Apple’s introduction of the remote locking feature in September 2013 as part of iOS 7. With iOS 8, Apple made its so-called said “kill switch” active by default, in accordance with California regulation, and that should help the rates of theft continue to trend downwards.

Apple’s Activation Lock requires a user to authorize a wipe or fresh install using the existing iCloud credentials on record, ensuring that a thief can’t go ahead and just wipe the device easily to use it themselves or prepare it for sale on the secondary market. Apple is one of the first major manufacturers to switch to implementing the system by default, rather than through user opt-in, which means it should be present on far more devices. All new iPhone 6 and 6 Plus units, for instance, will have it on be default given that they shipped with iOS 8 pre-installed.

Stats from last year indicated that Apple’s implementation of the Activation Lock were having a significant effect, but Apple’s combined iOS 8 adoption rate (currently at over 70 percent) and the fact that it’s now on by default means that the risk associated with stealing a modern iOS device is even greater. The aim is to make smartphone theft ultimately as futile as stealing a credit card, whereby a user ‘cancelling’ their hardware renders it ultimately useless.

Smartphone theft is often theft of opportunity, meaning a thief weighs reward vs. risk, including factors like how difficult it is to recoup an investment on something they’ve taken. Activation Lock doesn’t automatically render smartphones using it worthless to thieves, but it skews the value proposition considerably, and reduces reward (an iPhone sold for parts is worth far less than a fully functional unity, for instance).

Apple seems committed to coming up with new ways to protect user devices and data when it comes to theft, given its early pioneering of phone tracking tech via Find My iPhone. Patents awarded Apple have also described systems whereby the phone requires positive ID of the user to even display an unlock prompt, and tech which can monitor and report on unidentified users in the background.
