NTFS - Features - Encrypting File System (EFS)
... 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 ... The symmetric key that is used to encrypt the file is then encrypted with a public key that is associated with the user who encrypted the file, and this encrypted data is stored in ... file, the file system uses the private key of the user to decrypt the symmetric key that is stored in the file header ...
Hybrid Cryptosystem - Example
... cryptosystem, Bob does the following Obtains Alice's public key ... Generates a fresh symmetric key for the data encapsulation scheme ... Encrypts the message under the data encapsulation scheme, using the symmetric key just generated ...
Hybrid Cryptosystem
... In cryptography, public-key cryptosystems are convenient in that they do not require the sender and receiver to share a common secret in order to communicate securely (among other useful properties) ... computations and are thus generally much more inefficient than comparable symmetric-key cryptosystems ... the high cost of encrypting long messages in a public-key cryptosystem can be prohibitive ...
Windows Server 2000 - New and Updated Features - Encrypting File System
... 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 less time to encrypt and decrypt large amounts of data than ... The symmetric key used to encrypt the file is then encrypted with a public key associated with the user who encrypted the file, and this encrypted data is stored in the header of the encrypted file ... the file, the file system uses the private key of the user to decrypt the symmetric key stored in the file header ...
Modern Cryptography - Symmetric-key Cryptography
... Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable ... Symmetric key ciphers are implemented as either block ciphers or stream ciphers ... ciphers, in contrast to the 'block' type, create an arbitrarily long stream of key material, which is combined with the plaintext bit-by-bit or character-by-character ...
