Overview of external hard drives with hardware encryption diskAshur

Data security – not much happens. If the loss of data in a timely manner will save backup copies made, then here is the diversion of these things are much worse. How to protect themselves against loss of data when using external drives? Use drives with hardware encryption, such as diskAshur.


British company produces their iStorage, a portfolio that has a lot of similar solutions. On AppleInsider we wrote about their flash drive with encryption datAshur, now it’s time to talk about more serious decision – an external drive with encryption.

How does it work “apparently”?

Very simply, it is almost normal external HDD (available in quantities of up to XX XX), with a numeric keypad on the case. Until you enter the correct PIN code, no access to the data you get, and the system will not even see the disc. After entering the correct code – drive is connected, and can work with it as with a normal external HDD. After disconnecting the computer from the drive back is blocked. You can also set auto-lock after a delay if you are somewhere frequently absented himself and thus do not really trust colleagues.

How it works “inside”?

There is a simple scheme of the “protection”, which is used in cheap solutions. For example, just does not supply power to the disk before entering the password. Of course, this method costs are not easy, but very simply, understands body gets disk, and all data at a glance.

diskAshur works on a very different principle.

Inside the case of this disc is a special processor that encrypts all data stored on the drive using the AES algorithm with a 128 or 256-bit key (at the price of slightly different versions) [https://ru.wikipedia.org/wiki/Advanced_Encryption_Standard], also known under the name Rijndael. This is the standard encryption algorithm, which is used by many organizations and even the U.S. government. This processor generates a random key that is used for encryption encrypts the data that it stores the key and within themselves in a special memory area to which access can be obtained only by entering the correct PIN. If you entered the code correctly – the processor takes the key and decrypts the data, giving access to them. If the code is entered incorrectly 10 times – the key is deleted and all data remains inaccessible. Thus, even taking out drive, an attacker without knowledge of the PIN code will not be able to get anything.

Обратная сторона

There have diskAshur and additional features. It supports two types of accounts: administrator and user. The administrator can be only one, and users can define up to ten, each with its own pin number, it will use the drive in a corporate environment, if someone forgets the password of the users – the administrator can replace it.

You can specify a special “emergency” code, after entering this data will be “forgotten”, but access is blocked. There is also the possibility of a complete “reset” disk with reset all passwords and erase all data.

Intelligent drive electronics will protect the contents from a variety of attacks: brute-force attempts to read an electromagnetic pulse, and others.

In addition to filling a smart, diskAshur user will appreciate the practicality and convenience. It is designed as a conventional external hard drive is very small and nice looking. Body Material – black soft-touch plastic, the buttons are made of rubber, resistant to abrasion (by the way, another way to compromise your PIN – the worn buttons). USB-string – not replaceable, but tucked away in a slot on the side. For ease of portability manufacturers even put in a small bag set-cover.

Drive uses USB 3, and due to the fact it is encrypted at the hardware level, the velocity is close to conventional USB drives 3.

Of course, you can encrypt the contents of the disc and the software using, for example, a popular and reliable solution TrueCrypt, but a hardware solution in the face of diskAshur provides a number of advantages.

datAshur easier to use – just enter the PIN code, and all the work of key generation, encryption, and so on, he will take over.
datAshur help out in a situation where encryption program can not be established.
datAshur transparently works with all devices that support USB Mass Storage.
datAshur protected from keyloggers and trojans.

It is clear that not everyone needs such an exhaustive and reliable protection to overpay for it is not all you need, but to assess the damage from getting your data into the wrong hands it is worth. If it is more cost disk – their price starts at 11,800 rubles ( that’s the official online store in Russia ) – Buy it justify itself.
