    Learn what your Android encryption is for and if it's really useful

    It is true that by being careful about what we share on the Internet and avoiding malicious applications we can be safe, but there is still one last point, and if we lose our smartphone, all that information would be available to anyone, unless we encrypt Our device.

    What does the encryption of information contribute and how is it done?

    Android is an operating system that really takes the security section seriously. One of the most interesting security options is the encryption of information. This technique allows our data to be safe in case of loss or theft of our smartphone with a password. Without that password, if the person with our phone decides to reset it from the factory, all data will be deleted, preventing them from being dealt with.

    The encryption or encryption has been available for a long time (if I remember correctly, from Gingerbread), and to activate it is necessary to go to Settings-> Security and click on encrypt phone. Next we will give you to encrypt, being necessary a PIN or unlock pattern. It is a long process that can take about an hour, so be sure to keep your phone connected to the charger.

    Encrypt or not encrypt? That is the question

    As we have seen, the encryption of our phone makes it possible that if we lose our phone, make it impossible for others to access our personal information, although not everything is as good as it seems.

    With the arrival of the Nexus 6 and 9 came Lollipop, an ambitious version that came loaded with bugs and performance problems. Although the system was fluid, it was sometimes dubious, and the default encryption was partly responsible for this, because these devices incorporated it serially.

    The problem with today's encryption remains, reducing the performance of modern terminals such as the new Galaxy Note 5.

    Is it really necessary to encrypt information?


    It may seem after watching the previous video that the information encryption does not reduce both the performance so that it is mandatory to keep it off, although later on in daily use it ends up being noticed more and more.

    Knowing that encryption of information reduces the performance of our phone Is it really necessary that our information is encrypted?

    This question is something that each one must answer to itself. Is it worth losing performance of our phone to make sure that if we lose them nobody can see them? It is not the same as in our phone we have phone numbers and games to carry committed photos or bank details. Everyone knows what they have on their phone and if they would like other people to have access to this data.

    Will Marshmallow solve performance problems?

    Marshmallow is the latest version of Android released by Google, and although it may seem that not, this latest version has much to do with the well-known information encryption.

    That is what we can check in the compatibility document of Android 6.0 Marshmallow, where Google makes it clear to manufacturers that those who want to include the latest version of Android to their devices will have to meet a number of conditions, Mandatory.

    With Android Marshmallow we have seen that it has dramatically improved performance over Lollipop, and may have solved some errors that the encryption incorporated. But is it enough?

    The challenges of encrypting information to become mandatory

    Whether or not the encryption errors are solved, the fact is that Google has a great interest in imposing it on all its partners to make Android an ecosystem as safe as possible, and that is because every time we store more important information on our phones , And even more so when Android Pay is fully extended.

    As we have seen with the update to Marshmallow, it is possible to correct the software to reduce the difference, although the final result will never be as good as a device that has its hardware prepared for it. If Android pretends to be a system that does not lose performance with the information encryption, it will be necessary changes in the hardware.
    The first change is in the memories, because having our encrypted device requires a higher reading speed in the internal storage, which is quite improvable.

    Another point that we see of vital importance is that the new mobile processors are prepared for the cipher, causing that there are no yield losses. Processors like this already exist today like the NvidiaTegra K1 64-bit included in the Nexus 9, so that may be the way to go.

    What do you think about information encryption? Do you use it on your phone? Do you think that with mobile payments it is a good idea to get active from the factory?
