What is a hard disk encryption?

term Hard disk refers to the main storage used on the computer. There are several synonyms for the hard drive, including the disk drive and hard drive and The hard disk is an alternative spelling. Encryption means converting data to another form using an algorithm, which is inaccessible to anyone who does not have a secret key. Hard disk encryption refers to the act of encrypting the entire content of the computer's hard disk. Unlike file encryption, which only makes certain specific data, the rest is.

Hard disk encryption has several other names. It is known as encryption of the whole disk, full disk encryption, , encryption -which is also shortened as FDE, hard disk encryption , or simply disk encryption . Hard disk encryption has been considered a valuable security measure provided by the operating system or software program. He has a CT on any computer like a desktopUp to particularly useful for transmission computers, removable devices and other portable devices that leave the office and can be stolen or lost. For full functionality, it depends on that it has strong passwords, as well as the backup process that allows the network administrator to restore if the password is forgotten or the employee is released or leaves the organization. It can also be used in combination with verification measures such as Smart Card keyboard or biometric indicator.

Hard disk encryption was questioned in 2008 by publishing research by a project jointly supported by Princeton University and Electronic Frontier Foundation (EFF). Research has found that even when hard disk encryption, computer data can still be endangered because DRAM (dynamic memory with random access) maintained for a few seconds to a minute after the power loss, AI when DRAM is removedSkat encryption key and memory images. It has also been observed that when a user locks or suspends computer operations or inserts a computer into hibernation or sleep mode, RAM can be maintained and access. Efforts continue to increase safer data. In 2009, The Trusted Computing Group (TCG) - WHICH INCLUDES HARD DRIVE Manufacturers Fujitsu®, GST®, Hitachi®, IBM®, LSI®, Samsung®, Seagate®, ULINK®, Wave Systems®, and Western Digital® - Published and Hard Disk Encryption Standard Storage Specification Standard, That They Have All Agreed to and Whic Would Omit the Need for Software Encryption, Since the System Would Be Build into hard drives themselves, but it is not clear whether this concerns DRAM problems.
