Starting from the Windows 7 version at Lucker allows encryption not only of the basic in the system
disks but also of us b disks.
The solution is also called Bit locker to go
the general mechanism is exactly the same but does not require the TPM module.
In this case the TPM module is optional we can encrypt USP disks and the key there was encrypted will
be protected by a password and not stored in the TPM module.
The solution is relatively efficient.
We can encrypt a flash drive with a few gigabytes in about half an hour.
It takes about the same amount of time to decrypt it.
The use of such a flash drive means the reduction in efficiency of about 5 percent such as we mentioned
earlier the initial encryption of the entire area is quite time consuming but it can be cancelled at
any time.
Interestingly we can connect the flash drive encrypted in this way to earlier versions of Windows a
program code will be written on the flash drive allowing its decryption hence the name bit locker to
go detached program permits routing encrypted data but does not allow modification
such a flash drive only becomes a carrier for reading all computers with the exception of those with
the relevant addition of Windows 7
in conclusion.
We compare bit locker to true crypt.
These are solutions with similar functionality.
Both systems allow encryption of entire disks this functionality is based on the fact that operating
systems are not linked directly to a disk.
We have a hierarchical structure of layers and between these layers we can place additional programs
such as drive encryption programs.
This may be a layer between the physical disk and a partition or between a partition and a folder bit
locker as an original solution of Microsoft.
And sure it comes from your crypt foundation but lager is a little newer but it's commercial.
It's available only on selected versions of Windows Vista and later it does not allow hiding disks.
It does however allow authenticating the user by using a password key TPM module or any of their combinations.
In your script we only have a password or a key for the same reason but Lucker support is checking the
integrity of the computer and true crypt is not Lucker also allows for the generation of extra keys
for administrative reasons.
Neither of the two programs enable hardware based encryption only true crypto allows the encryption
of a physical disk in the lower layer blogger encrypts all partitions but not all of the physical disks
partitions can also be encrypted with true crypt encryption of virtual disks is characteristic of true
crypt as far as algorithms are concerned.
In the case of bit locker ABS has been chosen for us in the case of true crypt we can also choose the
algorithm ourself.
I'd recommend a yes an interesting thing is that we can encrypt the disk using several algorithms we
can encrypt data again a second time in regards to moding encryption Locher we have CBC as well as in
true crypt.
And I recommend selecting CBC
elephants as an original solution and bit locker to check the authenticity by diffusing bits circlip
partly verify the authenticity by such that a change in one bit of plain text causes a change of more
than one bit and the ciphertext knowing how it Lucker works.
Let's consider what we should not do so that after disk encryption the data saved on the disk could
actually be a secure.
