The Advanced Encryption Standard ( AES ) is a specification for the encryption of electronic data established by the U. S. National Institute of Standards and Technology ( NIST ) in 2002.

* Encryption is used to protect the message from the eyes of others.

The Data Encryption Standard ( DES, or ) is a previously predominant algorithm for the encryption of electronic data.

The discovery of differential cryptanalysis is generally attributed to Eli Biham and Adi Shamir in the late 1980s, who published a number of attacks against various block ciphers and hash functions, including a theoretical weakness in the Data Encryption Standard ( DES ).

In cryptography, the International Data Encryption Algorithm ( IDEA ) is a block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991.

IDEA is a minor revision of an earlier cipher, Proposed Encryption Standard ( PES ); IDEA was originally called Improved PES ( IPES ).

* Encryption systems usually require some synchronization mechanism to ensure that the receiving cipher is decoding the right bits at the right time.

In cryptography, Triple DES is the common name for the Triple Data Encryption Algorithm ( TDEA or Triple DEA ) block cipher, which applies the Data Encryption Standard ( DES ) cipher algorithm three times to each data block.

The Triple Data Encryption Algorithm ( TDEA ) is defined in each of:

In electric and gas utility SCADA systems, the vulnerability of the large installed base of wired and wireless serial communications links is addressed in some cases by applying bump-in-the-wire devices that employ authentication and Advanced Encryption Standard encryption rather than replacing all existing nodes.

Encryption for e-mail had already been in use for some time but is now the renewed focus of internal security practices for sending e-mail containing patient information.

* Encryption / SSL acceleration: when secure web sites are created, the SSL encryption is often not done by the web server itself, but by a reverse proxy that is equipped with SSL acceleration hardware.

Besides the GRE example above, native plaintext tunneling protocols include Layer 2 Tunneling Protocol ( L2TP ) when it is set up without IPsec and Point-to-Point Tunneling Protocol ( PPTP ) or Microsoft Point-to-Point Encryption ( MPPE ).

However, Central Directory Encryption feature is not supported.

The PPP payload is encrypted using Microsoft Point-to-Point Encryption ( MPPE ) when using MSCHAPv1 / v2 or EAP-TLS.

Encryption is the most common method to hide code.

Encryption alone is not polymorphism.

A widely-used and previously-developed cryptographic mechanism is the Data Encryption Standard, which was used primarily for the protection of electronic funds transfers.

Encryption, which is actually a part of cryptography, involves transforming texts or messages into a code which is unreadable.

There are techniques for creating ciphers on unusual or fractional block sizes ( i. e. domains whose size is not a power of two ); see Format-Preserving Encryption.

In cryptography, SEAL ( Software-Optimized Encryption Algorithm ) is a very fast stream cipher optimised for machines with a 32-bit word size and plenty of RAM.

* the Elliptic Curve Integrated Encryption Scheme ( ECIES ), also known as Elliptic Curve Augmented Encryption Scheme or simply the Elliptic Curve Encryption Scheme,

FIPS PUB 46-3 ( 1999 ) defines the " Triple Data Encryption Algorithm ( TDEA )", but also uses the terms " DES " and " Triple DES ".

Business based virtual worlds also may provide various enterprise features such as Single Sign on with third party providers, or Content Encryption.

Imation also released a version of the SuperDisk with " Secured Encryption Technology " which uses Blowfish with a 64-bit key to encrypt the contents.

In particular, the length of the output should be the same as the length of the input ( the picture on the right has S-boxes with 4 input and 4 output bits ), which is different from S-boxes in general that could also change the length, as in DES ( Data Encryption Standard ), for example.

The last official version of NetPositive before the Be, Inc. bankruptcy was 2. 2 / 2. 2. 1 for US customers, but there also exists a 3. 0d3 beta version, and a leaked 2. 2. 2 which changed from the RSA Encryption Engine to OpenSSL, possibly indicating that Be were cleaning the source of commercial code with an intent to open source, like the OpenTracker project.

Encryption will not only encrypt your messages, but also malware.

EFS works by encrypting a file with a bulk symmetric key, also known as the File Encryption Key, or FEK.

It has caused some controversy as it was claimed to have the potential to break the Advanced Encryption Standard ( AES ) cipher — also known as Rijndael — faster than an exhaustive search.

On-the-fly encryption ( OTFE ), also known as Real-time Encryption, is a method used by some encryption programs, for example, disk encryption software.

Despite being compromised also, the TPS Crypt system has been further modified to utilise Advanced Encryption System ( AES ) keys.

The Rijndael S-box is a matrix ( square array of numbers ) used in the Rijndael cypher, also known as the Advanced Encryption Standard ( AES ) cryptographic algorithm.

Encryption also helps to secure wireless networks.

XML Encryption, also known as XML-Enc, is a specification, governed by a W3C recommendation, that defines how to encrypt the contents of an XML element.

Encryption has long been used by militaries and governments to facilitate secret communication.

Encryption can be used to protect data " at rest ", such as files on computers and storage devices ( e. g. USB flash drives ).

, AES Encryption Information: Encryption Specification AE-1 and AE-2 in addition to the less secure PKZIP 2. 0 encryption method used in earlier versions.

* Expansion of support for authenticated encryption ciphers, used mainly for Galois / Counter Mode ( GCM ) and CCM mode of Advanced Encryption Standard encryption.

Fixed tables are normally used, as in the Data Encryption Standard ( DES ), but in some ciphers the tables are generated dynamically from the key ( e. g. the Blowfish and the Twofish encryption algorithms ).

A generalized Feistel algorithm can be used to create strong permutations on small domains of size not a power of two ( see Format-Preserving Encryption ).

Encryption is provided using the SSL / TLS protocol-layer, either in the traditional always-on mode used by HTTPS or using the HTTP Upgrade extension to HTTP ( RFC 2817 ).

This approach of alternatively applying substitution and permutation transformation has been used by IBM in the Lucifer cipher system, and has become the standard for national data encryption standards such as the Data Encryption Standard and the Advanced Encryption Standard.

* File Encryption Key ( FEK ): used to decrypt / encrypt each file's data ( in the primary NTFS stream )

Encryption is supported and used by some agencies on the network.

In cryptography, the Cellular Message Encryption Algorithm ( CMEA ) is a block cipher which was used for securing mobile phones in the United States.

In cryptography, a circulant matrix is used in the MixColumns step of the Advanced Encryption Standard.

* TETRA Encryption Algorithm, an encryption algorithm used in Terrestrial Trunked Radio

* XML Signature and XML Encryption, two other W3C standards used by the XKMS protocol.

Encryption using two-square is basically the same as the system used in four-square, except that the plaintext and ciphertext digraphs use the same matrices.

Courtois was one of the co-authors of both the XSL attack against block ciphers such as the Advanced Encryption Standard and the XL system for solving systems of algebraic equations, used in the attack.

* Advanced Encryption Standard process, the process used in choosing an algorithm for standardization as AES

In cryptography, Optimal Asymmetric Encryption Padding ( OAEP ) is a padding scheme often used together with RSA encryption.

Encryption is used to prevent eavesdropping on downstream traffic.
