How Does the Product Protect Confidential Data?

Dekart Private Disk MultiFactor allows you to create virtual secret disks in Windows and work with them as with conventional disks. A virtual Private Disk MultiFactor is no more than a usual file — a so-called disk image file, storing all of the encrypted data. After accessing the image file by means of Dekart Private Disk MultiFactor, the operating system detectsermines it as a normal disk and assigns to it a corresponding letter to it. For example, if your system had drives defined by the letters C: and D:, then the letters X:, Y: or any other will appear upon accessing the Private Disk MultiFactor. All of the programs that you are accustomed to working with will not be affected in any way when using a standard and virtual disks. For them, this will be just another hard disk. The image file of a virtual disk can have any name, extension, and access path (even a network paths are valid as well). Accessing the Private Disk MultiFactor and working with the secret data are is only possible only when the right electronic Key is available. This device stores the cryptographic data encryption key and the full name of the virtual Private Disk MultiFactor image file.

Installing Dekart Private Disk MultiFactor is easy, and should not take longer than 5 minutes. Dekart Private Disk MultiFactor is easy to operate — upon loading it will prompt two modes of access to Private Disk MultiFactors.

Simplified automatic mode. In this mode, inserting the electronic Key into the reader or attaching it to the USB port is enough to access the Private Disk MultiFactor. Disk access is discontinued when the Key is removed. In this mode, one-factor authentication is used and the security is not as strong as in the mode that follows.

Strong authentication mode. In this mode, two-factor authentication is used to access the Private Disk MultiFactor. The distinguishing feature from the simplified mode is that this mode provides strong protection: even if a third party obtains your Key, they will be unable to take advantage of it without your PIN.

Encrypting confidential information is easy — simply transfer it from any media (other disks or the same computer, or floppies, Zip drives, etc.) to the Private Disk MultiFactor and remember to store your new confidential data on this disk too, while storing non-sensitive information on any other disks. The Advanced Encryption Standard (AES) in CBC mode with 256 bit key length is used as the virtual disk encryption algorithm. Is this encryption key reliable? Yes! According to the estimates of Bruce Schneier, Applied Cryptography, fitting the encryption key 128 bit long requires 4.2x10^22 processors performing 256 million encryption operations per second. But even in this case, the key will be cracked in a year.
