Encrypting File System (EFS) in Windows Vista can be used to encrypt the system page file and the per-user Offline Files cache. EFS is also more tightly integrated with enterprise Public Key Infrastructure (PKI), and supports using PKI-based key recovery, data recovery through EFS recovery certificates, or a combination of the two.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
Filesystem-level encryption, [1] often called file-based encryption, FBE, or file/folder encryption, is a form of disk encryption where individual files or directories are encrypted by the file system itself. This is in contrast to the full disk encryption where the entire partition or disk, in which the file system resides, is encrypted.
EFS works by encrypting a file with a bulk symmetric key (also known as the File Encryption Key, or FEK), which is used because it takes a relatively small amount of time to encrypt and decrypt large amounts of data than if an asymmetric key cipher is used.
For improved network security, Windows Vista supports for 256-bit and 384-bit Diffie-Hellman (DH) algorithms, as well as for 128-bit, 192-bit and 256-bit Advanced Encryption Standard (AES) is included in the network stack itself, while integrating IPsec with Windows Firewall.
If you’re on Windows XP or Windows Vista, AOL suggests using the AOL Shield browser for optimal performance. A: AOL Desktop Gold, AOL Shield, and AOL Shield Pro requires users to have an existing internet connection.
Whereas prior releases of Windows supported per-file encryption using Encrypting File System, the Enterprise and Ultimate editions of Vista include BitLocker Drive Encryption, which can protect entire volumes, notably the operating system volume. However, BitLocker requires approximately a 1.5-gigabyte partition to be permanently not encrypted ...
EncFS is a Free FUSE-based cryptographic filesystem.It transparently encrypts files, using an arbitrary directory as storage for the encrypted files. [4] [5]Two directories are involved in mounting an EncFS filesystem: the source directory, and the mountpoint.
