What is a flight encryption?

flight encryption is a data security method on a computer storage device in a way that allows information to remain accessible to the verified user but protected on the unit itself. The characteristic feature of the on -site encryption scheme is that the information is read and written in coding, so there is no information that is not stored on a unit that is not protected and encrypted. Encryption and algorithms used for flight encryption must be very fast and completely automatic, so the user does not have to do anything more than to provide any type of verification to use encrypted disk and files. In general, a unit that is protected in this way must use special systems to access data, which means that some encryption software is not necessarily transmitted from one system to another if the software is not installed in advance. The most commonly used encryption that is defined as a flight in cases where storage mediumThe removable, portable or can be otherwise accessible or stolen at any point, which requires the data to be stored at all times.

In computer security, encryption means receiving otherwise normal data or files and processing it in a way, so the information and potentially the name of the file itself become unreadable and unusable for a person who has no key or password that can decrypt the data. There are many types of encryption algorithms, some of which require a fair amount of time for large files. The flight encryption process uses real -time encryption algorithms to encrypt and decrypt the file while accessing.

When the flight encryption is in force and the user wants to load and change the file, the first thing that occurs is that the file is read and quickly decrypted from the medium of physical storage. The decoded file is not written to any permanent place but instead of itIt is szatloučed in the memory of random access (RAM). Once the user is made with the file, the changes are handed over to the encryption software and the software writes it directly to the storage medium as an encrypted file. The only time when uneven information is exposed is when it is held in RAM.

In addition to file encryption and directory, encryption can also be used to encrypt the entire disk and its file system. This means that something like the thumb unit could be completely inaccessible to someone who has not installed the right software and keys to display it. Some very safe setting settings on flight-like is a security card, a special removable media key, or a real cryptographic processor chip inside the computer-in the fact can be used physical verification.
