Over the past few years we have heard about the smartphone encryption – this is an area where the details matter. Drive Encryption date back at least to the beginning of 1990 – ies. The actual encryption can be done in one of two different ways (Full Disk Encryption (FDE) system based on encryption file (NEP) system). Most of the software for commercial PC disk encryption historically decided to use the approach, full disk encryption (FDE). Basically it’s just a question of expediency: FDE simply much easier to implement.
Early attempts to Android, with the addition of encryption on their phones follow a standard PC encryption full disk paradigm. The problem is that smartphones are not PCs.
Apple , in turn, encrypts all the data stored on the device. But unlike Android, Apple doesn’t use the full-disk encryption paradigm. Instead, they employ a file-based encryption approach that individually encrypts each file on the device. Apple’s approach isn’t perfect.
New Androide all files are divided into two types: encrypted (available after entering the security code) and are available immediately after loading device.
You may have noticed that when Apple’s, had four categories of protection, Android N has only two. This missing two categories, which cause problems.
As a result, in 2016 Android is still trying to deploy encryption, which reaches (lock screen) security that Apple has figured out six years ago.
Although Android is clearly moving in the right direction. At the same time there is a lot of work to be done, even half-baked implementation of the implementation on the basis of better files than the latest generation of silent encryption FDE Android.
